The level structure of 122Sb

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

“…The J~ limits resulting from the present study (Table2) are generally consistent with these assignments (which only extend to 0.5 MeV), although several states observed in the (p, n 7) reaction are not observed in the (t7, d) reaction. It is clear from the (n, 7) reaction study of Atexeev et al [8] and from earlier [4,6] (n, },) and (p, nT) reaction work that many of the peaks observed in the (p, d) reaction are in fact multiplets. Since negative-parity states of ~z~ will generally involve the hl~/2 neutron, they will not be readily observed in the (p, at) reaction due to the unfavorably high/-transfer of 5 h required for the transition.…”

“…In at least some cases, such as the 8.4 keV 2 and 260 keV 3 levels, the unobserved states have negative parity. For example, the 264 keV t= 5 transition (Table 3) probably includes the 264 keV 5 and 265 keV 7-states observed by Alexeev et al [8]. Above 0.5 MeV, very little is known about *Z~ only the very uncertain (d, t) reaction [9] results are available.…”

“…The levels of the odd-odd Sb isotopes should result from p-n interactions involving these orbitals. [7] and the 121Sb(n, 7)iZ2Sb study of Alexeev et al [8]. Most of the available spectroscopic information on both nuclei results from recent 7-ray spectroscopic studies, in particular the I2~ rQ')lZ~ study of Adachi et at.…”

“…Most of the available spectroscopic information on both nuclei results from recent 7-ray spectroscopic studies, in particular the I2~ rQ')lZ~ study of Adachi et at. 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). However, the 121Sb(d, t) [9], t23Sb(d, t) [9,10], and t21Sb(d,p) [9,10] single-neutron transfer reactions have also been studied, albeit with rather poor resolution and only at a few angles (No angular distributions at all are reported in [10]).…”
