Via the reaction ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(e, p_0){}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ cross sections for the transition ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(\gamma , p_0){}_{}{}^{15}{}_{}{}^{}\mathrm{N}$ have been extracted at angles ${\theta }_p=5\mathrm{}°-40\mathrm{}°$. Whereas a modified quasideuteron model fails to describe the data, a calculation of Gari and Hebach with the inclusion of spin currents comes close to the results.

NUCLEAR REACTIONS ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(e, p_0){}_{}{}^{15}{}_{}{}^{}\mathrm{N}$, $E_e=80\mathrm{}$ MeV, measured ${\sigma }_e(E_e, \theta )$, deduced ${\sigma }_{\gamma }(E_{\gamma }, \theta )$; BeO target.
