Study of the excitation of high-spin isomers in 190Ir and 196,198Au in the near-threshold region

Abstract

The isomeric ratios of the yields for 190m,gIr and 196m,gAu have been measured in the (γ,n) reaction in the near-threshold region at γ-ray energies of 12 and 12.5 MeV. The isomeric ratios for 198m,gAu have been measured in the (d,p) and (n,γ) reactions. The statistical nature of the (γ,n) and (n,γ) reactions is shown.
