"63mNi" and "65mNi" are excited isomers of the two respective isotopes.
See "The NUBASE evaluation of nuclear and decay properties" at: http://www.nndc.bnl.gov/amdc/nubase/Nubase2003.pdf Pages 6-9 describe isomer definitions. Pages 42-43 include excitation energies and half-lives for both of these Ni-isomeric isotopes. I wonder if isomeric isotopes might have beta-decay modes which regular isotopes do not.
