Efficiency of high-purity germanium detector at characteristic gamma energies of 198Au and 58Co and covariance analysis

Abstract

Naturally occurring 197Au and 58Ni foils were subjected to the neutron irradiation by placing them in a dry tube-I of Kalpakkam Mini reactor to produce gamma emitting 198Au and 58Co nuclear reaction products. The efficiency study of high-purity germanium detector corresponding to characteristic gamma energies 0.4118 and 0.8107 MeV of 198Au and 58Co was carried out by the methods of calibration of 152Eu and covariance.
