Abstract

Photonuclear reactions on a natural mixture of mercury isotopes were investigated by the activation method at an electron energy of \(E^{m}=55\) MeV. The reaction yields as well as the isomeric ratios for \({}^{195,197}\) Hg and \({}^{198,200}\) Au were determined. The results are compared with theoretical predictions from the TALYS 2.0 code. Based on both the present experimental and available literature data, the systematics of isomeric ratios as a function of spin factors were obtained for heavy nuclei in the \(Z=60{-}80\) range.
