62NI c 1971JoZN (thesis) (also 1969Jo07, 1974Jo11): source from {+62}Ni(p,n),
62NI2c E=7, 13 MeV, and from decay of {+62}Zn parent. Measured E|g, I|g,
62NI3c and conversion electrons using a double-focusing magnetic spectrometer.
62NI4c 1969Jo07 reported four gamma rays and intensity of 511 annihilation
62NI5c radiation, but the latter is revised in 1971JoZN. More details can
62NI6c be found in the thesis (1971JoZN). A table of E|g and I|g values
62NI7c from 1971JoZN is also reproduced in 1974Jo11.
62NI c 1970Va11: source from {+62}Ni(p,n),E=6.8 MeV; measured E|g, I|g for
62NI2c nine |g rays, and the intensity of annihilation radiation.
62NI c 1969Es03: source from {+62}Zn parent produced in Cu(p,2n); measured
62NI2c E|g, I|g for five |g rays
62NI c 1975Ca40: source from {+63}Cu(n,2n),E=14 MeV. Measured E|g, I|g for
62NI2c seven |g rays, and the intensity of annihilation radiation.
62NI c Others studies:
