Photodisintegration of $^{80}$Se, $^{94}$Zr, and $^{108}$Pd as a probe of neutron capture for radioactive nuclei

Abstract

Photoneutron cross sections were measured for 80 Se near the neutron separation energy with the laser Compton scattering γ rays. The stellar neutron capture rate for 79 Se was evaluated by using the photodisintegration data as constraints on the E1 γ strength function within the framework of the Hauser-Feshbach statistical model. The result is compared with the model calculation of Bao and Käppeler.
