63CO c 1985Ru05: {+63}Fe source was produced via W({+82}Se,X) with E=11.5
63CO2c MeV/nucleon {+82}Se beam from the UNILAC accelerator on a 46 mg/cm{+2}
63CO3c natural tungsten target at GSI. Fragments were separated with the GSI
63CO4c on-line mass separator and transported to a measuring position inside a
63CO5c 4|p plastic |b-detector between two opposite Ge detectors. Measured
63CO6c E|g, I|g, |b|g-coin, |g|g-coin. Deduced levels, J, |p, |b-decay
63CO7c branching ratios, log {Ift}. Comparisons with available data.
63CO8c See also 1983Ru06 from the same lab for an earlier measurement using
63CO9c W({+76}Ge,X) E=9 MeV/nucleon, which is superseded by 1985Ru05.
63CO c The decay scheme is considered incomplete due to a large gap between
63CO2c Q-value=6216 and the highest observed level at E=3422 and unplaced
63CO3c |g transitions.
63CO cB IB$From I|g intensity balance at each level, unless otherwise noted.
63CO2cB Due to the incomplete decay scheme, the quoted values of I|b and
63CO3cB log {Ift} should be considered as approximate.
63CO cG $Note that 1364.7|g assigned as a g.s. transition by 1983Ru06 has
63CO2cG been re-assigned to be from {+63}Co decay to {+63}Ni.
63CO cG E,RI$From 1985Ru05
63CO cL E$From a least-squares fit to |g-ray energies
63CO cL J,T$From Adopted Levels.
63FE P 0.0 5/2- 6.1 S 6 6216 19
63FE cP J,T$From Adopted Levels of {+63}Fe. Adopted T{-1/2} is taken from
63FE2cP 1985Ru05 (superseding 4.9 s {I5} in an earlier measurement in 1983Ru06)
63FE cP QP$From 2021Wa16
63CO N 0.14 1.0 1.0
63CO cN NR$From |S%I|g(|g to g.s.)=100-%I|b{+-}(g.s.), with %I|b{+-}(g.s.)=80
63COxcN from 1985Ru05 (see comments for I|b(g.s.)).

63CO cB IB$from comparison of |b singles and |b|g-coin spectra (1985Ru05). The
63CO2cB authors of 1985Ru05 state that the direct g.s. |b feeding (%I|b=80) is
63CO3cB taken from their earlier measurement in 1983Ru06 (%I|b(g.s.)=76 {I26})
63CO4cB after correction for the new values of relative |g-ray intensities in
63CO5cB 1985Ru05. Note that both 1985Ru05 and 1983Ru06 deduced %I|b values by
63CO6cB assuming their decay scheme is complete, that is, %I|b(g.s.)+|S%I|g(|g
63CO7cB to g.s.)=100 for observed and placed |g transitions. However, the
63CO8cB proposed decay scheme is incomplete and their deduced I|b should be
63CO9cB considered as approximate, while the large I|b{+-} still can imply
63COacB this decay branch is strong and allowed.
