Isomeric Ratios of ( g ,p) and ( g , a ) Reactions on 117 m , g In

The isomeric ratios of the ( γ ,p) and ( γ , α ) reactions on 117 m , 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. DOI: 10.3103/S1062873808110294
