2017-06-23T10:00:00-04:00

Author(s): R. Caballero-Folch et al.
Background: There have been measurements on roughly 230 nuclei that are β-delayed neutron emitters. They range from ^{8}He up to ^{150}La. Apart from ^{210}Tl, with a branching ratio of only 0.007%, no other neutron emitter has been measured beyond A=150. Therefore, new data are needed, particularly...

Calculation of Gamow-Teller and two-neutrino double-β decay properties for ^{130}Te and ^{136}Xe with a realistic nucleon-nucleon potential

2017-06-23T10:00:00-04:00

Author(s): L. Coraggio, L. De Angelis, T. Fukui, A. Gargano, and N. Itaco

The authors tackle the important subject of nuclear matrix elements governing double-β decay in a first-principles shell-model calculation. They derive the shell-model effective interaction and the Gamow-Teller transition operator from a realistic nucleon-nucleon interaction. The procedure is tested on the two-neutrino double-β decays of 130Te and 136Xe for which experimental data exist. This test precedes an application to the neutrino\textit{less} double-β decay of the same nuclei.

Multiplicity derivative: A new signature of a first-order phase transition in intermediate-energy heavy-ion collisions

2017-06-22T10:00:00-04:00

Author(s): S. Mallik, G. Chaudhuri, P. Das, and S. Das Gupta

The thermodynamic properties of nuclear matter can be probed by collisions between heavy nuclei at various energies, and then studying the resulting nuclear fragment distributions. The authors propose an observable which will indicate that nuclear matter has undergone a first-order liquid-gas phase transition. That observable is based on the total multiplicity of the fragmenting system (its first derivative) for collisions between heavy nuclei, and is directly accessible by experiments. It maximizes at the same energy as the specific heat, Cv, which typically happens at any first-order phase transition. Other potential indicators of a phase transition are less indicative due to the long-range Coulomb interaction and the fact that the atomic nucleus has a finite size.

Electroexcitation of nucleon resonances of the [70,1^{−}] multiplet in a light-front relativistic quark model

2017-06-13T10:00:00-04:00

Author(s): I. G. Aznauryan and V. D. Burkert
We utilize the light-front relativistic quark model to predict the 3q core contribution to the electroexcitation of nucleon resonances of the [70,1^{−}] multiplet on the proton and neutron at Q^{2}<5GeV^{2}. The investigation is motivated by new experimental data from continuous electron beam accelerator facility large acceptance spectrometer on meson electroproduction for a wide range of the hadronic invariant mass including the full third nucleon resonance region up to sqrt[s]=1.8 GeV. For the states N(1520)3/2^{−},N(1535)1/2^{−}, and N(1675)5/2^{−}, experimental results on the electroexcitation amplitudes on the proton are available for a wide range of Q^{2}. This allowed us also to quantify the expected meson-baryon contributions to these amplitudes as a function of Q^{2}.

Net reaction rate and neutrino emissivity for the Urca process in departure from chemical equilibrium

Doubly magic ^{208}Pb: High-spin states, isomers, and E3 collectivity in the yrast decay

2017-06-12T10:00:00-04:00

Author(s): R. Broda, R. V. F. Janssens, Ł. W. Iskra, J. Wrzesinski, B. Fornal, M. P. Carpenter, C. J. Chiara, N. Cieplicka-Oryńczak, C. R. Hoffman, F. G. Kondev, W. Królas, T. Lauritsen, Zs. Podolyak, D. Seweryniak, C. M. Shand, B. Szpak, W. B. Walters, S. Zhu, and B. A. Brown

The nucleus 208Pb provides an iconic test of the nuclear shell model because its 82 protons and 126 neutrons are both magic numbers. When excited levels are discovered and characterized, this nucleus provides a means to investigate the mechanisms responsible for the generation of angular momentum and, ultimately, for the development of collectivity. This experiment is a tour de force that reveals extensive new information on 208Pb about high-angular-momentum states, isomeric states, and collective states of octupole nature; thus it serves as a showcase for shell-model descriptions. Many of the states explored show good overall agreement with theory, but others at the highest energies reveal discrepancies, pointing to the need for improved calculations. Above the highest-lying 28 isomer γ transitions arising from yet higher spin levels could be identified in two separate experiments as displayed in the figure.

Vorticity of matter generated in noncentral heavy-ion collisions at energies of the Nuclotron-based Ion Collider fAcility (NICA) at the Joint Institute for Nuclear Research (JINR) in Dubna is studied. Simulations are performed within the model of the three-fluid dynamics (3FD) which reproduces the m...

Author(s): J. E. García-Ramos, P. Pérez-Fernández, and J. M. Arias
Background: Composed systems have become of great interest in the framework of ground-state quantum phase transitions (QPTs) and many of their properties have been studied in detail. However, in these systems, the study of the so-called excited-state quantum phase transitions (ESQPTs) has not receiv...

Author(s): K. Schmidt et al.
The deexcitation of alpha-conjugate nuclei produced in reactions of 35 MeV/nucleon ^{40}Ca with ^{40}Ca has been investigated. Particular emphasis is placed on examining the dynamics of collisions leading to projectile-like fragment exit channels. A general exploration of the reaction systematics re...

Author(s): V. V. Sargsyan, G. G. Adamian, N. V. Antonenko, W. Scheid, and H. Q. Zhang
The experimental fusion excitation functions of the reactions ^{48}Ti+^{58}Fe and ^{58}Ni+^{54}Fe, measured down to the low sub-barrier energies, are described within the quantum diffusion approach and the universal fusion function representation. For these systems, the s-wave capture probabilities ...

New and efficient method for solving the eigenvalue problem for the two-center shell model with finite-depth potentials

2017-05-30T10:00:00-04:00

Author(s): K. Hagino and T. Ichikawa
We propose a method to solve the eigenvalue problem with a two-center single-particle potential. This method combines the usual matrix diagonalization with the method of separable representation of a two-center potential; that is, an expansion of the two-center potential with a finite basis set. To ...

Using the coalescence model based on nucleons from a blast-wave model with its parameters fitted to the measured proton transverse momentum spectrum and elliptic flow in heavy-ion collisions at the Relativistic Heavy Ion Collider, we study the elliptic flows of light nuclei in these collisions. We f...

Author(s): Michito Okai, Koji Kawaguchi, Yasuki Tachibana, and Tetsufumi Hirano
We propose a new approach to initialize the hydrodynamic fields, such as energy density distributions and four-flow velocity fields in hydrodynamic modeling of high-energy nuclear collisions at the collider energies. Instead of matching the energy-momentum tensor or putting the initial conditions of...

Author(s): G. I. Gakh, M. I. Konchatnij, N. P. Merenkov, and E. Tomasi-Gustafsson
The differential cross section for elastic scattering of protons on electrons at rest is calculated, taking into account the QED radiative corrections to the leptonic part of interaction. These model-independent radiative corrections arise due to emission of the virtual and real soft and hard photon...

Author(s): L. Frankfurt, V. Guzey, and M. Strikman
We explore the theoretical observation that within the leading twist approximation, the nuclear effects of shadowing and antishadowing in nonperturbative nuclear parton distribution functions (nPDFs) at the input QCD evolution scale involve diffraction on nucleons of a nuclear target and originate f...

Author(s): C. J. Yang, M. Grasso, K. Moghrabi, and U. van Kolck
Phenomenological effective interactions like Skyrme forces are currently used in mean-field calculations in nuclear physics. Mean-field models have strong analogies with the first order of the perturbative many-body problem and the currently used effective interactions are adjusted at the mean-field...

Activity measurement of ^{60}Fe through the decay of ^{60m}Co and confirmation of its half-life

The half-life of the neutron-rich nuclide ^{60}Fe has been in dispute in recent years. A measurement in 2009 published a value of (2.62±0.04)×10^{6} years, almost twice that of the previously accepted value from 1984 of (1.49±0.27)×10^{6} yr. This longer half-life was confirmed in 2015 by a second m...
