E(level): From γ-ray studies when possible. Energies of levels populated only in particle-transfer reactions taken from 62Ni(t,3He) and 64Ni(d,α) for levels below 2.8 MeV, and from 64Ni(pol d,α) for higher energies
M(γ): From γ(θ) in 48Ca(18O,p3nγ)

62Co produced and identified by 1949Pa01 in 64Ni(d,α) and 62Ni(n,p) reactions followed by chemical separation. Later studies: 1957Ga15, 1968Ki08, 1969Wa16, 1969Mo04, 1969Es03, 1970Jo12
Other reactions:
1995Wi09: 62Ni(n,p) E=198 MeV; measured summed Gamow-Teller strength functions up to 30 MeV excitation energy
1987Ah01: 63,65Cu(n,X) E=9,11 MeV; measured cross sections and level-density parameter
1987Gl05: 64Ni(7Li,7Be) E=78 MeV; measured σ, deduced particle-hole gross structure
1984Br03: 62Ni(n,p) E=60 MeV; measured σ(θ), deduced analog isovector resonance excitation mechanism
1984Ul01: 62Ni(n,p) E=59.6 MeV; measured σ(θ), deduced GDR analog, sum rule and blocking
1979Gr16: 66Zn(α,8B) E=109 MeV; measured σ(θ); possible observation of 62Co g.s. population.
