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-$\beta$ 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-$\beta$ decays of ${}^{130}$Te and ${}^{136}$Xe for which experimental data exist. This test precedes an application to the neutrino\textit{less} double-$\beta$ 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, ${C}_{v}$, 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.

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}.

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 ${}^{208}$Pb 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 ${}^{208}$Pb 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 $\gamma$ transitions arising from yet higher spin levels could be identified in two separate experiments as displayed in the figure.

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 ...

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...
