abstract = {he  transition strengths of the T=1 isobaric triplet Kr, Br, Se, recently measured at RIKEN/RIBF, are discussed in terms of state of the art large scale shell model calculations using the JUN45 and JUN45+LNPS plus Coulomb interactions. In this letter we argue that, depending on the effective charges used, the calculations are either in line with the experimental data within statistical uncertainties, or the anomaly happens in Br, rather than Kr. In the latter case, we suggest that it can be due to the presence of a hitherto undetected 1 T=0 state below the yrast 2 T=1 state. Our results do not support a shape change of Kr with respect to the other members of the isobaric multiplet.},

abstract = {In this review, we describe the experimental facilities and methods which make it possible to produce and measure the properties of the extreme neutron rich nuclei. We then develop the theoretical framework that will accompany us along the review; the shell-model approach with large scale configuration interaction (mixing) SM-CI, with special emphasis in the competition between the spherical mean field and the nuclear correlations (mainly pairing and quadrupole-quadrupole). The symmetry properties of the latter are treated in detail as they will show to be of great heuristic value. We explore in detail the Islands of Inversion (IoI) at N=20 and N=28. We make a side excursion into the heavier Calcium and Potassium isotopes, to discuss current issues on shell evolution and new magic numbers far from stability. We visit the N=40 Island of Inversion. We discuss the doubly magic nucleus 78Ni, its shape coexistence and the prospect of a new IoI at N=50 below Z=28. We examine the N=70 and N=82 neutron closures approaching the neutron drip line.},

With this erratum, we clarify that a choice was made in 2018 to consider the latest γ-ray intensities available and obtain the M (E2) value for the 2+→ 0+ decay in 50Mn. Here, we consider the current evaluated relative γ-ray intensities given in the National Nuclear Data Center (NNDC)[2], ie, 100 (9) and 64 (8) for the 149-and 800-keV γ decays, respectively. This new analysis lowers the data point for 50Mn given in this paper by 20% with a value of 28 efm2 as shown in Fig. 1 (green square).},

abstract = {Background: The evolution of shell structure around doubly magic exotic nuclei is of great interest in nuclear physics and astrophysics. In the ‘southwest’region of Ni 78, the development of deformation might trigger a major shift in our understanding of explosive nucleosynthesis. To this end, new spectroscopic information on key close-lying nuclei is very valuable.

Purpose: We intend to measure the isomeric and β decay of Co 75, with one-proton and two-neutron holes relative to Ni 78, to access new nuclear structure information in Co 75 and its β-decay daughters Ni 75 and Ni 74.

Methods: The nucleus Co 75 is produced in relativistic in-flight fission reactions of U 238 at the Radioactive Ion Beam Factory in the RIKEN Nishina Center. Its isomeric and β decay are studied exploiting the BigRIPS and EURICA setups.

Results: We obtain partial β-decay spectra for Ni 75 and Ni 74, and report a new isomeric transition in …},

abstract = {The region of neutron-rich Cr isotopes has garnered much attention in recent years due to a rapid onset of collectivity near neutron number N= 40. We report here on the first γ-ray spectroscopy beyond the (4+ 1) state in 62, 64Cr, using nucleon removal reactions from several projectiles within a rare-isotope beam cocktail. A candidate for the 6+ state in 64Cr is presented as well as one for, possibly, the second excited 0+ state in 62Cr. The results are discussed in comparison to the LNPS shell-model predictions that allow for neutron excitations across the N= 40 harmonic oscillator gap into the g9/2 and d5/2 orbitals. The calculated level schemes for 62, 64Cr reveal intriguing collective structures. From the predicted neutron particle-hole character of the low-lying states in these Cr isotopes, 62Cr emerges as a transitional system on the path to the center of the N= 40 island of inversion.},

abstract = {Situated in the so-called “island of inversion,” the nucleus 32Mg is considered as an archetypal example of the disappearance of magicity at N=20. We report on high statistics in-beam spectroscopy of 32Mg with a unique approach, in that two direct reaction probes with different sensitivities to the underlying nuclear structure are employed at the same time. More specifically, states in 32Mg were populated by knockout reactions starting from 33Mg and 34Si, lying inside and outside the island of inversion, respectively. The momentum distributions of the reaction residues and the cross sections leading to the individual final states were confronted with eikonal-based reaction calculations, yielding a significantly updated level scheme for 32Mg and spin-parity assignments. By fully exploiting observables obtained in this measurement, a variety of structures coexisting in 32Mg was unraveled. Comparisons with theoretical predictions based on shell-model overlaps allowed for clear discrimination between different structural models, revealing that the complete theoretical description of this key nucleus is yet to be achieved.},
