Abstract

Coulomb energy differences between mirror nuclei with A 70 are calculated within the framework of the nuclear shell model using an effective Coulomb plus isovector and isotensor interaction. Absolute binding energies for proton-rich nuclei are predicted by adding the calculated Coulomb shifts to experimentally measured binding energies for the neutron-rich mirror. The location of the proton drip-line is investigated, as well as candidates for the exotic decay mode known as di-proton emission. Taking into account the lifetimes of competing decay modes and limits imposed by experimental setups, it is concluded that the best candidates for the observation of correlated di-proton emission are 45Fe, 48Ni, and 63Se.
