Study of radionuclides created by /sup nat/Ni(. gamma. ,xn yp) reactions for bremsstrahlung photons produced by 140-MeV electrons
Twelve radionuclides from /sup 48/V to /sup 57/Ni 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 /sup 56/Ni and /sup 57/Ni. For /sup 56/Ni, T/sub 1/2/ = 6.08 +- 0.03 days, in agreement with previous measurements. For /sup 57/Ni, 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 /sup 57/Ni 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.
