First-excited state g factor of ^{136}Te by the recoil in vacuum method
2017-07-27T10:00:00-04:00
Author(s): A. E. Stuchbery, J. M. Allmond, M. Danchev, C. Baktash, C. R. Bingham, A. Galindo-Uribarri, D. C. Radford, N. J. Stone, and C.-H. Yu
Electromagnetic properties of atomic nuclei such as $E2$ transition rates and $M1$ magnetic moments (or $g$ factors) are crucial characteristics of structure. For unstable nuclei produced as reaccelerated radioactive beams, measurements of $g$ factors present numerous challenges. This paper develops the important recoil-in-vacuum technique to obtain a $g$ factor for the ${2}^{+}$ state in ${}^{136}$Te. The result fits existing systematics but also highlights anomalous values in other $N=84$ isotones, thus presenting an important challenge to theory in the region just above doubly magic ${}^{132}$Sn.

Nuclear deformation in the A≈100 region: Comparison between new masses and mean-field predictions

The nuclear mass region around $\approx 100$ is one of the most important for understanding the origin of non-spherical shapes in heavy nuclei, as well as the evolution from spherical to deformed shapes as a function of neutron and proton number. Precise mass measurements are often key to delineating such regions of structural change. The present paper, using state-of-the-art Penning-trap and time-of-flight mass spectrometry techniques, further maps out the locus of shape change in this region through measurements of new masses, particularly in the rubidium isotopes. The results, and accompanying theoretical calculations, point to the importance of further mass measurements in the neighboring krypton isotopes, promising key insights into the evolution of competing prolate and oblate shapes.

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.

The observed one- and three-quasiparticle bands in ^{133}Cs, built on the πh_{11/2},πg_{7/2}, ...

In-beam γ-ray spectroscopy of the neutron-rich platinum isotope ^{200}Pt toward the N=126 shell gap
2017-06-22T10:00:00-04:00
Author(s): P. R. John
et al.The neutron-rich nucleus ^{200}Pt is investigated via in-beam γ-ray spectroscopy to study the shape evolution in the neutron-rich platinum isotopes towards the N=126 shell closure. The two-neutron transfer reaction ^{198}Pt(^{82}Se, ^{80}Se)^{200}Pt is used to populate excited states of ^{200}Pt. Th...

Relative fragmentation in ternary systems within the temperature-dependent relativistic mean-field approach
2017-06-22T10:00:00-04:00
Author(s): M. T. Senthil Kannan, Bharat Kumar, M. Balasubramaniam, B. K. Agrawal, and S. K. Patra
For the first time, we apply the temperature-dependent relativistic mean-field (TRMF) model to study the ternary fragmentation of heavy nuclei using the level density approach. The relative fragmentation probability of a particular fragment is obtained by evaluating the convolution integrals that em...

Unexpected distribution of ν1f_{7/2} strength in ^{49}Ca
2017-06-21T10:00:00-04:00
Author(s): H. L. Crawford
et al.The calcium isotopes have emerged as a critical testing ground for new microscopically derived shell-model interactions, and a great deal of experimental and theoretical focus has been directed toward this region. We investigate the relative spectroscopic strengths associated with 1f_{7/2} neutron h...

Statistical moments in superposition models and strongly intensive measures
2017-06-21T10:00:00-04:00
Author(s): Wojciech Broniowski and Adam Olszewski
First, we present a concise glossary of formulas for composition of standard, cumulant, factorial, and factorial cumulant moments in superposition (compound) models, where final particles are created via independent emission from a collection of sources. Explicit mathematical formulas for the compos...
