General Comments:

1985Gu14: first evidence for production of 62Cr in Ti,Ta(86Kr,X) at E=33 MeV/nucleon; energy loss and time-of-flight methods.

1990Tu01, 1994Se12: mass measurements by time-of-flight method; Th(p,F) production method

1998Am04: 62Cr produced in fragmentation of 86Kr beam at 500 MeV/nucleon hitting a Be target at GSI facility. First measurement of isotopic half-life.

1999So20 (also 1999Le67): 62Cr produced in 58Ni(86Kr,X), E=60.4 MeV/nucleon at GANIL facility using LISE3 doubly achromatic spectrometer. Measured Eγ, Iγ, βγ coin, isotopic half-life from β decay timing.

2003So02 (also 2002MaZN thesis,2003So21, 2005Ga01): 62V produced in 58Ni(76Ge,X), E=61.8 MeV/nucleon at GANIL facility using LISE3 doubly achromatic spectrometer. Measured β, γ, isotopic half-life from β decay timing.

2009Cr02: Be(76Ge,X) E=130 MeV/nucleon, measured production yield

Q-value: Note: Current evaluation has used the following Q record

Q-value: ΔS(p)=520, ΔQ(α)=605 (syst,2011AuZZ)

Q-value: Q(β-n)=3256 337, S(2n)=10053 399, S(2p)=33447 685 (syst) (2011AuZZ)

Q-value: Values in 2003Au03: Q(β-)=7620 400, S(n)=6310 420, S(p)=18340 520 (syst), Q(β-n)=3070 410, S(2n)=10050 400, S(2p)=33350 870 (syst)
