“…We have investigated the likelihood of observing excited states of 5 H in the (d, 3 He) reaction by calculating the spectroscopic overlaps between 6 He and different 5 H(J π ) configurations using both shellmodel, and ab-initio calculations with the variationalMonte-Carlo (VMC) and Green's function Monte Carlo (GFMC) techniques [53,54]. The shell-model calculations used the WBT interaction [55] and were performed using the code NUSHELLX [56]. Table III lists threshold.…”

We have studied the ground state of the unbound, very neutron-rich isotope of hydrogen 5 H, using the 6 He(d, 3 He) 5 H reaction in inverse kinematics at a bombarding energy of E( 6 He)=55A MeV. The present results suggest a ground-state resonance energy ER=2.4±0.3 MeV above the 3 H+2n threshold, with an intrinsic width of Γ=5.3±0.4 MeV in the 5 H system. Both the resonance energy and width are higher than those reported in some, but not all previous studies of 5 H. The previously unreported 6 He(d, t) 5 Heg.s. reaction is observed in the same measurement, providing a check on the understanding of the response of the apparatus. The data are compared to expectations from direct two-neutron and dineutron decay. The possibility of excited states of 5 H populated in this reaction is discussed using different calculations of the 6 He→ 5 H+p spectroscopic overlaps from shell-model and ab-initio nuclear-structure calculations.

“…The results of different shell model calculations for 21 C and 22 C are shown in Figure 7 together with the experimental level scheme for 20 C and the recently measured S 2n for 22 C. We performed calculations with NuShellX@MSU [33] labeled WBP*. In this interaction the neutron sd two body matrix elements (TBME) were reduced to 0.75 of their original value in order to reproduce a number of observables in neutron rich carbon isotopes [29].…”

Search for 21C and constraints on 22C

et al. 2013

A search for the neutron-unbound nucleus 21 C was performed via the single proton removal reaction from a beam of 22 N at 68 MeV/u. Neutrons were detected with the Modular Neutron Array (MoNA) in coincidence with 20 C fragments. No evidence for a low-lying state was found, and the reconstructed 20 C+n decay energy spectrum could be described with an s-wave line shape with a scattering length limit of |a s | < 2.8 fm, consistent with shell model predictions. A comparison with a renormalized zero-range three-body model suggests that 22 C is bound by less than 70 keV.

“…The 13/2 + state has not yet been observed in 133 Sn and the energy reported in Table I has been estimated from that (2.434 MeV) of the experimental 10 + state in 134 Sb, assumed to belong to the πg 7/2 νi 13/2 configuration. The shell-model calculations have been performed by using the OXBASH code [20].…”

Evolution of single-particle states beyond132Sn

et al. 2013

We have performed shell-model calculations for the two one valence-neutron isotones 135 Te and 137 Xe and the two one valence-proton isotopes 135,137 Sb. The main aim of our study has been to investigate the evolution of single-particle states with increasing nucleon number. To this end, we have focused attention on the spectroscopic factors and the effective single-particle energies. In our calculations, we have employed a realistic low-momentum two-body effective interaction derived from the CD-Bonn nucleon-nucleon potential that has already proved quite successful in describing the spectroscopic properties of nuclei in the 132 Sn region. Comparison shows that our results reproduce very well the available experimental data. This gives confidence in the evolution of the single-particle states predicted by the present study.
