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.

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.

Analytic predictions for nuclear shapes, prolate dominance, and the prolate-oblate shape transition in the proxy-SU(3) model

Author(s): Dennis Bonatsos, I. E. Assimakis, N. Minkov, Andriana Martinou, S. Sarantopoulou, R. B. Cakirli, R. F. Casten, and K. Blaum
Using a new approximate analytic parameter-free proxy-SU(3) scheme, we make simple predictions of shape observables for deformed nuclei, namely γ and β deformation variables, the global feature of prolate dominance, and the locus of the prolate-oblate shape transition. The predictions are compared w...

Author(s): Toshihiro Nonaka, Masakiyo Kitazawa, and ShinIchi Esumi
We derive formulas for the efficiency correction of cumulants with many efficiency bins. The derivation of the formulas is simpler than the previously suggested method, but the numerical cost is drastically reduced from the naïve method. From analytical and numerical analyses in simple toy models, w...

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-$\beta$ 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$l\phantom{\rule{0}{0ex}}e\phantom{\rule{0}{0ex}}s\phantom{\rule{0}{0ex}}s$ double-$\beta$ decay of the same nuclei.

We show the important role played by the πΔ(1232) channel in the build up of the N(1700)(3/2^{−}) resonance due to the nontrivial enhancement produced by a singularity of a triangular loop.

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.
