Photonuclear Studies for the Isomeric Yield Ratios in the Production of natFe(,xnp)52m,gMn with 50-,60-, and 70-MeV Bremsstrahlung

Abstract

The isomeric yield ratios in the production of natFe(,xnp)52m,gMn have been measured with photonuclear reactions. The high purity natural Fe metallic foils were used and irradiated with bremsstrahlung beams of end point energy 50-, 60-, and 70-MeV. The bremsstrahlung beams are produced with high energy electron beam struck with 0.1 mm thin tungsten target. The activation method has been used and hence the induced activities in the irradiated foils were measured by off-line -ray spectrometric technique using HPGe detector coupled to a PC-based 4K MCA. The experimental values of isomeric ratios are compared with the theoretical values by statistical model code TALYS. The detail of the formation of isomers by photonuclear reactions together with the literature values of the investigated nuclides are compared and discussed.
