Isomeric ratios of (γ,p) and (γ,α) reactions on 117m,gIn

The isomeric ratios of the (γ,p) and (γ,α) reactions on 117m,g In have been measured. The ratios Y m /Y g was found to be 1.18(9) and 0.23(9), respectively, at a boundary energy of 22 MeV. The statistical character of the reactions under such conditions is shown.
