Two Proton Knockout from $^{32}$Mg

We present data and calculations on the near-dripline nucleus $^{30}$Ne. Gamma-ray decays from excited states as well as inclusive and exclusive cross-sections were measured in the $^{9}$Be($^{32}$Mg,$^{30}$Ne $\gamma )$X two-proton knockout reaction at incident beam energies of 99.7 and 86.7 MeV/A. The measured inclusive cross section sigma = 0.22(4)mb is suppressed compared to calculation and is indicative of a reduced overlap of initial and final state wavefunctions. We interpret this reduction as a result of large 4p4h intruder components present in $^{30}$Ne, but not $^{32}$Mg. Large 4p4h amplitudes are predicted to generate increased T=1 paring strengths and to help stabilize the heavier fluorine isotopes against neutron decay. A new gamma-ray transition at 1443 keV is assigned to the decay of the 4$^{+}$ state based on the spin dependent sigma for 2 proton knockout from the (d5/2)$^{4}$ configuration.
