“…It is noted that our level scheme disagrees with the scheme proposed by Wang et al [17] based on a low-statistics γ-ray singles spectrum obtained in multinucleon transfer. Wang et al suggest that the 904 keV γ-ray transition reported in intermediate-energy Coulomb excitation [14], although they did not observe it in their own work, corresponds to the decay of the 9/2 − state to the ground state.…”

“…Furthermore, SDPF-U level schemes are available in the literature for 39 S [38], 40 S [18], and 41 S [17]. In contrast to SDPF-MU, the SDPF-U effective interaction consists of two parts, one valid for Z ≤ 14 and one applicable to Z ≥ 15 [25].…”

“…Gamma-ray spectroscopy following, for example, β decay [19], intermediate-energy Coulomb excitation [14], multinucleon transfer reactions [17,18,20], and projectile fragmentation [15,16] provided a first, limited glimpse of the level structure of the neutron-rich S isotopes approaching N = 28 [23]. Here, we report on the in-beam γ-ray spectroscopy of 38−42 S following the fragmentation of 46 Ar and 48 Ca intermediate-energy projectile beams on a C target in the center of the GRETINA γ-ray spectrometer [24].…”

“…These effects are included in the SDPF-MU effective shell-model interaction introduced in [3] and the resulting predictions for the 40,41,42 S level schemes will be tested in the present work. The sulfur isotopes between N = 20 and N = 28 have been studied with a variety of experimental techniques [10][11][12][13][14][15][16][17][18][19][20], however, information on the level schemes even at low excitation energy is still scarce. Beyond N = 28, very few excited states have been reported in the S isotopic chain [21,22].…”

The low-energy excitation level schemes of the neutron-rich 38−42 S isotopes are investigated via in-beam γ-ray spectroscopy following the fragmentation of 48 Ca and 46 Ar projectiles on a 12 C target at intermediate beam energies. Information on γγ coincidences complemented by comparisons to shell-model calculations were used to construct level schemes for these neutron-rich nuclei. The experimental data are discussed in the context of large-scale shell-model calculations with the SDPF-MU effective interaction in the sd-pf shell. For the even-mass S isotopes, the evolution of the yrast sequence is explored as well as a peculiar change in decay pattern of the second 2 + states at N = 26. For the odd-mass 41 S, a level scheme is presented that seems complete below 2.2 MeV and consistent with the predictions by the SDPF-MU shell-model Hamiltonian; this is a remarkable benchmark given the rapid shell and shape evolution at play in the S isotopes as the broken-down N = 28 magic number is approached. Furthermore, the population of excited final states in projectile fragmentation is discussed.

“…Recently, charge screening from both ionized nuclei and electrons in relativistic electronpositron plasmas have been discussed and applied to the determination of thermonuclear reaction rates [13,14]. This effect turned out to be negligible during the BBN epoch because the plasma is in a high temperature, low density state, and the distance between electrons or positrons and nuclei is so large that the screening effect on the Coulomb potential is not significant.…”

Screening corrections to electron capture rates and resulting constraints on primordial magnetic fields

et al. 2020

We explore screening effects arising from a relativistic magnetized plasma with applications to Big Bang nucleosynthesis (BBN). The screening potential which depends on the thermodynamics of charged particles in the plasma is altered by the magnetic field. We focus on the impact of screening on the electron capture interaction. Taking into account the correction in BBN arising from a homogeneous primordial magnetic field (PMF), we constrain the epoch at which the PMF was generated and its strength during BBN. Considering such screening corrections to the electron capture rates and using up-to-date observations of primordial elemental abundances, we also discuss the possibility of solving the problem of under-estimation of the deuterium abundance. We find for certain values of the PMF strength predicted D and 4 He abundances are both consistent with the observational constraints.
