Abstract

The (gamma,n) reaction rates of the isotopes Hg-196,Hg-198,Hg-204 and Pb-204 have been determined using the photoactivation technique in an energy region relevant for p process nucleosynthesis. The systematic study of the ground-state (gamma,n) reaction rates on even-even nuclei in the mass region Zgreater than or equal to78 is complemented with these experiments. The data are compared to rates predicted in the framework of two statistical model approaches.
