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