General Comments:

1983Ru06: 62Mn identified in W(76Ge,X) at 9 MeV/nucleon; mass separation. Assignment based on the agreement between the energy of the most intense 877-keV γ transition and the energy of the first excited level of 62Fe measured in the 64Ni(14C,16O) and (18O,20Ne) reactions, and the decay of the 877-keV γ and β- rays

Structure calculations: 2010Sr03, 2005Ga01

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

Q-value: Q(β-n)=2668.2 37, S(2n)=11355.7 35, S(2p)=30182 475 (2011AuZZ)

Q-value: Values in 2003Au03: Q(β-)=10860 220, S(n)=4550 320, S(p)=13150 340, Q(β-n)=2810 220, S(2n)=11000 240, S(2p)=30040 520
