摘要：

We report on the in-beam gamma spectroscopy of Sn-102 and Cd-100 produced via two-neutron removal from carbon and CH2 targets at about 150 MeV/nucleon beam energy. New transitions assigned to the decay of a second 2(+) excited state at 2470(60) keV in Sn-102 were observed. Two-neutron removal cross sections from Sn-104 and Cd-102 have been extracted. The enhanced cross section to the 2(2)(+) in Sn-102 populated via the (p, p2n) reaction is traced back to an increase of shell-model structure overlaps, consistent with the hypothesis that the proton-induced two-deeply bound-nucleon removal mechanism is of direct nature.
