Author(s): K. Wei (魏康) and H. F. Zhang (张鸿飞)The concept of cluster radioactivity has been extended to allow emitted particles with ${Z}_{C}>28$ for superheavy nuclei by nuclear theory [Poenaru et al., Phys. Rev. Lett. 107, 062503 (2011)]. The preformation and emission mechanics of heavy-ion particles must be examined again before the fasc...

Author(s): K. Fossez, J. Rotureau, N. Michel, and W.

In this work, we investigate ground...

Author(s): B. Schuetrumpf, W. Nazarewicz, and P.-G.

For instance, bubble structures in superheavy nuclei are believed to be due to the electrostatic repulsion. In light nuclei, the mechanism behind the de...

Author(s): Kosho Minomo, Michio Kohno, Kazuki Yoshida, and Kazuyuki OgataWe propose to use proton knockout reactions $(p,2p)$ from a deeply bound orbit as a new probe into three-nucleon-force (3NF) effects.

Author(s): J. A. Melendez, S. Wesolowski, and R. J. FurnstahlChiral effective field theory (EFT) predictions are necessarily truncated at some order in the EFT expansion. Bayesian analysis has been proposed as a means to quantify the theoretical uncertainties that are induced by that truncation, in order to provide a robust statistical comparison with experiment. The authors apply a Bayesian model to an extended set of observables calculated for a class of EFT interactions, and demonstrate that a subset of these potentials are consistent with their statistical model for order-by-order convergence.

Author(s): S. A. Gillespie, A. Parikh, C. J. Barton, T. Faestermann, J. José, R. Hertenberger, H.-F. Wirth, N. de Séréville, J. E. Riley, and M. WilliamsIsotope ratios in meteoritic inclusions or grains can help identify the astrophysical origin of the grain. In particular the ${}^{34}$S/${}^{32}$S ratio has been suggested as an optimal observable for this. Depending on the rate of proton capture on ${}^{34}$S one may be able to distinguish between nova and supernova origin. The authors observed 10 new levels in the compound nucleus (${}^{35}$Cl) and have reduced the uncertainty in the capture cross section. They propose that the ${}^{34}$S/${}^{32}$S isotope ratio can be used as a nucleosynthesis marker.

Author(s): R. Honda et al. (J-PARC E10 Collaboration )Hypernuclei, in which a proton or neutron in an atomic nucleus is replaced by a baryon that includes some number of valence strange quarks, are a unique probe of nuclear structure as well as of the strong interaction. This work provides significantly improved cross section data as well as missing-mass spectra in search of a possible ground state of the ${}_{\mathrm{\Lambda}}^{6}$H hypernucleus, whose existence had been suggested in an earlier experiment using a different reaction. While the new experiment had considerable sensitivity, the authors observed zero events in the mass range of the previous experiment, suggesting that the binding energy of this hypernucleus is not as large as previously suggested.

YuElectromagnetic 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.

Schweikhard, A. Welker, F. Wienholtz, R. N. Wolf, and K. ZuberThe 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.
