Continuum particle-vibration coupling method in coordinate-space representation for finite nuclei

“…goes beyond the scope of the current paper, and in the following we shall limit ourselves to a simple comparison with the spectroscopic factors reported in the experimental papers [34,35]. Our results are comparable to those obtained in Ref.…”

“…They are compared with the experimental spectroscopic factors taken from Refs. [34,35]: these are represented in histogram form and also convoluted with Lorentzian functions of width 0.4 MeV (red solid curve). In the left (right) panels the energy of the renormalized HF + PVC 1d 3/2 (1f 7/2 ) state already displayed in Figs.…”

First in-beamγ-ray study of the level structure of neutron-richS39

“…In some cases, the lowest state of such a (j ) 3 configuration has a total angular momentum quantum number of J = j − 1, rather than J = j . This is a consequence of the residual interaction between the three like nucleons in the same orbit and was first discussed by Talmi in 1962 [48] [52] is based on systematics. In the present work, the assumption is made that the ground-state J π value is 7/2 − but, as is also the case for the 37 Si ground state, no definitive model-independent assignment has so far been made.…”

“…The excitation energy of the first 2 + state of 38 S is 1292 keV [55] and this suggests that a particle-core coupling description is appropriate for the 1517-keV J π = (11/2 − ) state of 39 S. in relation to the odd-A isotopes is rather sparse. The data presented in the figure were taken from Nuclear Data Sheet references [49,52,[55][56][57][58][59][60][61][62][63][64][65][66][67][68][69][70][71][72]. For the isotopes of sulfur and argon, the figure shows a good correlation between the behavior of the excitation energy of the first 2 + states of the even-A isotopes and the excitation energy differences of the first 11/2 − and first 7/2 − states of the odd-A isotopes with neutron number.…”

“…4). Population of the state in 37 Si at 717 keV by the removal of a 1d 3/2 neutron with a spectroscopic factor of C 2 S = 1.5 [43] and the weak population (C 2 S = 0.06) of the equivalent state at 1035 keV in the 40 Ar(d,p) 41 A reaction [52] are consistent with the main component of the wave function corresponding to ν(1d 3/2 ) 3 (1f 7/2 ) 4 . Such positive-parity states lie outside the 0 ω configuration space of the present shell-model calculations.…”
