Cluster preformation law for heavy and superheavy nuclei


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...

Continuum effects in neutron-drip-line oxygen isotopes


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

The binding-energy pattern along the neutron-rich oxygen chain, governed by an interplay between shell effects and many-body correlations impacted by strong couplings to one- and two-neutron continua, make these isotopes a unique testing ground for nuclear models. In this work, we investigate ground...

Bayesian truncation errors in chiral effective field theory: Nucleon-nucleon observables


Author(s): J. A. Melendez, S. Wesolowski, and R. J. Furnstahl

Chiral 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.

First measurement of the $^{34}\mathrm{S}(p,γ)^{35}\mathrm{Cl}$ reaction rate through indirect methods for presolar nova grains


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. Williams

Isotope ratios in meteoritic inclusions or grains can help identify the astrophysical origin of the grain. In particular the 34S/32S ratio has been suggested as an optimal observable for this. Depending on the rate of proton capture on 34S one may be able to distinguish between nova and supernova origin. The authors observed 10 new levels in the compound nucleus (35Cl) and have reduced the uncertainty in the capture cross section. They propose that the 34S/32S isotope ratio can be used as a nucleosynthesis marker.

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 Λ6H 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.

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 136Te. 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 132Sn.

The nuclear mass region around 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.

A new array of four Deuterated Benzene (${\mathrm{C}}_{6}{\mathrm{D}}_{6}$) detectors has been installed at the Gaerttner Linear Accelerator Center at Rensselaer Polytechnic Institute for the purpose of measuring neutron capture cross sections in the keV region. Measurements were performed on sample...

Fission fragment yield distribution in the heavy-mass region from the $^{239}\mathrm{Pu}$ (${n}_{\mathrm{th}},f$) reaction


Author(s): Y. K. Gupta, D. C. Biswas, O. Serot, D. Bernard, O. Litaize, S. Julien-Laferrière, A. Chebboubi, G. Kessedjian, C. Sage, A. Blanc, H. Faust, U. Köster, A. Ebran, L. Mathieu, A. Letourneau, T. Materna, and S. Panebianco

The fission fragment yield distribution has been measured in the $^{239}\mathrm{Pu}\left({n}_{\mathrm{th}},f\right)$ reaction in the mass region of $A=126$ to 150 using the Lohengrin recoil-mass spectrometer. Three independent experimental campaigns were performed, allowing a significant reduction o...

Possibilities of production of transfermium nuclei in complete fusion reactions with radioactive beams


Author(s): Juhee Hong, G. G. Adamian, and N. V. Antonenko

The possibilities of direct production of new isotopes of transfermium nuclei $^{261,263,264}\mathrm{No}$, $^{263,264}\mathrm{Lr}$, $^{263,264,266,268}\mathrm{Rf}$, $^{264,265}\mathrm{Db}$, and $^{267,268,270,272}\mathrm{Sg}$ are studied in various asymmetric hot fusion-evaporation reactions with ra...

Core-corona interplay in Pb-Pb collisions at $\sqrt{{s}_{\mathit{NN}}}=2.76$ TeV


Author(s): M. Petrovici, I. Berceanu, A. Pop, M. Târzilă, and C. Andrei

A simple approach based on the separation of wounded nucleons in an $A\text{−}A$ collision in two categories, those suffering single collisions (corona) and the rest (core), estimated within a Glauber Monte Carlo model, explains the centrality dependence of the light flavor hadron production in Pb-P...

Transition from vibrational to rotational character in low-lying states of hypernuclei


Author(s): H. Mei, K. Hagino, J. M. Yao, and T. Motoba

In order to clarify the nature of hypernuclear low-lying states, we carry out a comprehensive study of the structure of ${}_{\phantom{00000.}\mathrm{Λ}}^{145\text{–}155}\mathrm{Sm}$ hypernuclei, which exhibit a transition from vibrational to rotational character as the neutron number increases. To t...
