1975Fr16: identification and production of 62Fe in 64Ni(n,2pn) reaction at E(n)=25-200 MeV, neutron beam of the 200-MeV LINAC at BNL. Identification from monitoring of decay of 62Fe and growth of 62Co. Measured Eγ, half-life
Delayed neutron decay of 63Mn is allowed and, in principle, can populate levels in 62Fe, but there is no experimental information available for this decay mode
