In two-neutron pickup from 14O, the calculated cross-section ratio for the first two 0+ states of 12O depends on the configuration mixing in these two states, and on the amount of core excitation in the ground state (g.s.) of 14O. Using mirror symmetry and 12Be wave functions that are reasonably well known, I have calculated this ratio as a function of the core excitation in 14O(g.s.). Results suggest that the excited-state cross section from a recent measurement is too large.

I examine the properties of 11Li and the low-lying resonances in 10Li, as they relate to neutron removal from 11Li. Comparison with results from a recent 11Li(p,d) reaction strongly suggests that that experiment observed only the 2+ resonance, and not the 1+.

For proton removal from 13B to bound and unbound states of 12Be, I investigate the consequences of core excitation in both nuclei, using wave functions determined previously. Conclusions are that the ground state contains most of the 0+ strength, but the 2+ strength is concentrated in the second 2+ state, which is currently unknown, but predicted near 5 MeV.
