Abstract

Measurements on the polarized-proton capture reaction ${}^{15}N (p, γ_{0}) {}^{16}O$ indicate a broad $E 2$ resonance which lies above the giant $E 1$ resonance of ${}^{16}O$ . The measurements show that the $E 2$ radiation for the ( $γ, p_{0}$ ) channel of ${}^{16}O$ exhausts approximately 30% of the quadrupole sum rule.
