The 120Sn(p, d)119Sn reaction at 26.3 MeV

Interweaving of elementary modes of excitation in superfluid nuclei through particle-vibration coupling: Quantitative account of the variety of nuclear structure observables

“…Consequently, it can undergo accidental degeneracy and thus conspicuous fragmentation. As seen from Table II, although the calculated summed cross sections (σ = 6.15 mb) agree, within experimental errors, with observation (7.93 ± 2 mb), theory predicts an essentially uniform fragmentation of the strength over an energy interval of ≈760 keV, while the data [47] are consistent with a concentration of the strength at an energy close to that of the lowest theoretical 5/2 + level.…”

“…In discussing the 120 Sn(p,d) 119 Sn reaction [47] we concentrate on the d 5/2 orbital, the most theoretically challenging of all of the valence single-particle strength functions. This is because this state, being farther away from the Fermi energy ( d 5/2 = −11.3 MeV, F ≈ −8 MeV) than the other four valence orbitals ( g 7/2 = −10.1, s 1/2 = −9.0, d 3/2 = −8.5, and h 11/2 = −7.1 MeV), is embedded in a denser set of doorway states (of type…”

“…In the NG calculations the d 5/2 single-particle orbit in the SLy4 mean-field potential has been shifted toward F by 0. + ) reaction lying below 2 MeV, calculated using the NG equation and the bare SLy4 single-particle levels in comparison with the data [47]. The energies (in keV) are listed in the first (fourth) column, while the absolute cross sections (in mb) are given in the second (fifth), integrated within the range 2…”

Fast neutron emission from the energy region of the giant quadrupole resonance

“…The actual value of the differential cross-section is obtained by summing up each single-particle contribution which is calculated according to Eq. (50) and multiplied by the corresponding spectroscopic factor for each singleparticle state 9 As the spectroscopic factors, we use those obtained by the 12~ experiment [28], Table 7. …”

A study of the121,123Sb(p, d) reactions

“…[7] and the 121Sb(n, 7)iZ2Sb study of Alexeev et al [8]. In addition to providing additional level energies and J~ assignments, our main purpose in the present study of the 121,123Sb(p ' d) reactions is to investigate configuration mixing in 12o, 122Sb" From our analysis of the spectroscopic factors we also estimate occupation probabilities for the various neutron orbitals for comparison to 12~ [3]. On the basis of these data a large number of J~ and (especially in 122Sb) configuration assignments have been made (summarized in [7] for 12~ and [8] for 12ZSb).…”
