Abstract

A survey of the available single-proton data in $A \leq 17$ nuclei was completed. These data, along with calculations using a Woods-Saxon potential, show that the ordering of the $0 d_{5 / 2}$ and $1 s_{1 / 2}$ proton orbitals are determined primarily by the proximity of the $s$ -state proton energy to the Coulomb barrier. This is analogous to the dependence of the corresponding neutron orbitals in proximity to the neutron threshold, which was previously discussed.
