Photoelectric disintegration of 16O

Abstract

The photoelectric cross section of ${}^{16}$O($\gamma$,$\alpha$)${}^{12}$C is estimated to be larger than the radiative capture cross section of ${}^{12}$C($\alpha$ ,$\gamma$)${}^{16}$O. The predicted cross section and the angular distribution of $\alpha$-particle are illustrated for the future experiment. The cross section just above the $\alpha$-particle threshold is found to be dominated by the $E$2 excitation.
