Abstract

We report on the in-beam gamma spectroscopy of Sn102 and Cd100 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 Sn102 were observed. Two-neutron removal cross sections from Sn104 and Cd102 have been extracted. The enhanced cross section to the 22+ in Sn102 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.
