Study of radionuclides created by /sup nat/Ni(γ,xn yp) reactions for bremsstrahlung photons produced by 140-MeV electrons

Creators

Description

Twelve radionuclides from 48V to 57Ni produced by photon interactions with a sample of elemental Ni have been studied to obtain relative yields of these reaction products. Precision half lives were determined for 56Ni and 57Ni. For 56Ni, T/sub 1/2/ = 6.08 +- 0.03 days, in agreement with previous measurements. For 57Ni, T/sub 1/2/ = 35.54 +- 0.05 h, in agreement with the 1982 measurement of Grutter but approx. 0.5 h shorter than earlier measurements. relative yields of the 127-keV, 1758-keV, and 1919-keV gamma rays following decay of 57Ni were determined with respect to the 1338-keV gamma ray of that decay and the results agree better with measurements of Grutter and of Gatrousis et al. than they do with the Lederer et al. evaluation
