Abstract

Population of certain states seen in recent high-resolution photoproton spectra of ${}^{12}C$ , ${}^{16}O$ , and ${}^{40}{Ca}$ at photon energies between 61 and 77 MeV was taken as evidence for photoabsorption by T=1 proton-neutron pairs. This Comment suggests that the results might be more simply explained by the presence of admixed ground states in these nuclei.
