87NB c 1997Hu07: {+58}Ni({+32}S,2pn), E({+32}S)=170 MeV; measured half-life
87NB2c and proton-|g coincidences.
87NB c 1991Mi15: {+58}Ni({+32}S,2pn), E({+32}S)=105 MeV; measured |g
87NB2c singles, |g|g and |b|g coincidences, half-lives of the |g's,
87NB3c and conversion electrons.
87NB c 1983Ha06: {+58}Ni({+32}S,2pn), E({+32}S)=122 MeV; measured delayed
87NB2c protons and proton-|g coincidences and {+87}Mo half-life.
87NB c 1982De43: {+58}Ni({+32}S,2pn), |b|g coincidences with 263 |g with
87NB2c T{-1/2}=15 s 2, measured E{-|b}.
87NB c 1977Ko05: {+58}Ni({+32}S,2pn), E({+32}S)=111 MeV, observed 263-keV
87NB2c |g with T{-1/2}=14.1 s 2 and 397 |g with T{-1/2}=12.4 s 5.
87NB c Decay scheme is from 1991Mi15.
87NB c Since this decay has a Q value of over 6 MeV and the only
87NB2c observed levels are below 0.5 MeV, the scheme is clearly
87NB3c incomplete. Therefore, the |e intensities are upper limits and
87NB4c log{Ift} values are lower limits.
87NB c Some of the levels in the {+87}Nb daughter decay by the
87NB2c emission of protons to levels in {+86}Zr. From proton-752 |g
87NB3c (the 2{++} to ground state |g) coincidences, 1983Ha06 deduce
87NB4c 15% {I8} of the decays produce this |g ray. From proton-752
87NB5c |g coincidences, 1997Hu07 deduce the feeding of the 2{++},
87NB6c 4{++}, and 6{++} levels in {+86}Zr to be 11% {I6}, 2% {I1},
87NB7c and 2% {I1}, respectively.
87NB c Decay scheme is from 1991Mi15, using level energies from the Adopted
87NB2c Levels
87NB cE Since this decay has a Q value of over 6 MeV and the only
87NB2cE observed levels are below 0.5 MeV, the scheme is clearly
87NB3cE incomplete. Therefore, the |e intensities are upper limits and
87NB4cE log{Ift} values are lower limits.
