Population of bound and unbound states of 12Be in proton removal from 13B

Abstract

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.
