摘要：

gamma-ray decays from excited states in Ne-30 and inclusive and exclusive cross sections were measured in the Be-9(Mg-32, Ne-30 + gamma) X two-proton knockout reaction at incident beam energies of 99.7 and 86.7 MeV/nucleon. Themeasured cross section is suppressed compared to calculations and is indicative of a reduced overlap of initial and final state wave functions in Mg-32 and Ne-30. We interpret this reduction as due to large 4p4h amplitudes present in the Ne-30 ground state wave function, but not Mg-32. Such large intruder components are predicted to help stabilize the heavier fluorine isotopes against neutron emission.
