62NI c 1970Jo12 (also 1971JoZN thesis): {+62}Co from {+64}Ni(d,|a),E=16 MeV,
62NI2c using enriched {+64}Ni target at the Vrije University AVF cyclotron.
62NI3c Measured E|g, I|g, E|b, I|b, |b|g-coin, and half-life of
62NI4c {+62}Co g.s. using Ge(Li) detectors and an NE102 plastic scintillator.

62NI6c {+61}Cu, {+62}Cu and {+61}Co.

62NI2c neutron generator using natural Ni target. Measured E|g, I|g, |g|g-coin
62NI3c using Ge(Li) and NaI(Tl) detectors. Eleven |g rays reported.

62NI c Total decay energy of 5324 keV {I44} deduced (by RADLIST code) from
62NI2c proposed decay scheme is in agreement with the expected value of
62NI3c 5322 keV {I19}, indicating that decay scheme is complete
