The isomeric ratios in (n, γ) neutron capture reactions on 108Pd and 110Pd nuclei

Abstract

The isomeric ratios in neutron capture reactions, induced by thermal, resonant and mixed thermal-resonant neutrons on 108 Pd and 110 Pd nuclei have been measured by the activation method. The data analysis and necessary corrections as the self-absorption and summing cascade effects were made in gamma rays radioactivity measurements to improve the precision of the isomeric ratio determination. The results were discussed and compared with those in the existing literature. The isomeric ratios in 108 Pd(n, γ) 109m,g Pd and 110 Pd(n, γ) 111m,g Pd reactions, induced by mixed thermal-resonant neutrons as well as in 110 Pd(n, γ) 111m,g Pd reaction, induced by resonant neutron are first measurements.
