Cross-sections for formation of 73Ga through natGe(n, x)73Ga reaction induced by d-T neutrons

Abstract

The formation of ⁷³Ga through ^natGe(n,x)⁷³Ga reaction induced by d-T neutrons was investigated using cross-sections measured by four characteristic gamma-rays employing the weighted average method. The neutron energy and uncertainty were determined by the Q equation of reaction ³H(d,n)⁴He combined with the solid angle of the sample. The gamma spectrum of the activated sample was obtained by an off-line technique using a high-resolution, high-purity germanium detector (HPGe). The contribution of nuclear reactions ⁷⁶Ge(n,α)⁷³Zn, ⁷³Ge(n,p)⁷³Ga, and ⁷⁴Ge(n,d∗)⁷³Ga to residual nuclei ⁷³Ga was analyzed and the cross-sections of reaction ⁷³Ge(n,p)⁷³Ga were determined with a small uncertainty. The TALYS-1.96 package was utilized for performing the theoretical calculation of the cross section of ⁷⁶Ge(n,α)⁷³Zn, ⁷³Ge(n,p)⁷³Ga, and ⁷⁴Ge(n,d∗)⁷³Ga reactions. The results of the theoretical calculation of nuclear reaction ⁷³Ge(n,p)⁷³Ga were compared with the experimental measurements and the evaluation results provided by the database.
