190OS c 1974Ya02 (also 1974YaZU, 1972Da07): activities of the {+190} g.s. were
190OS2c from the IT decay of {+190}Re isomer in equilibrium with the |b{+-}
190OS3c decay of the isomer, with the isomer produced by the {+190}Os(d,|a)
190OS4c reaction using 18 MeV deuterons provided by the ANL 152-cm cyclotron on
190OS4c a 50-mg target of natural osmium. |g rays were detected with Ge(Li)
190OS5c detectors. Measured E|g, I|g, |g|g-coin, |g(t). Deduced levels, J, |p,
190OS6c parent T{-1/2}, configurations, |g-ray multipolarities, |b-decay
190OS7c branching ratios. Comparisons with theoretical calculations. 1974Ya02
190OS8c also report data on {+190}Ir |e decay (11.78 d) and {+189}Os(d,p)

190OS c Total deposit energy of 3058 keV {I130} calculated by RADLIST code is
190OS2c in agreement with expected value of Q(|b{+-})=3125 keV {I5}.

190OS cB IB$From I(|g+ce) intensity balance at each level, unless otherwise
190OS2cB noted.
190OS cG $Combined intensities given under comments are the total |g intensities
190OS2cG for the 3.1-h (isomer) and 3.0-min (g.s.) activities in equilibrium
190OS3cG (1974Ya02), where applicable.
190OS cG E$From 1974Ya02, obtained by the author from weighted averages when
190OS2cG possible from {+190}Ir |e decay (11.78 d) and {+190}Re |b{+-} decay
190OS3cG (3.2 h and 3.1 min). 28 unplaced weak |g rays, belonging to {+190}Re
190OS4cG (3.1 min) and/or {+190}Re (3.2 h) are given in {+190}Re |b{+-} decay
190OS5cG (3.2 h)
190OS cG RI$From decomposition (by evaluators) of the combined intensities
190OS2cG given by 1974Ya02 for the 3.1-h (isomer) and 3.0-min (g.s.) activities
190OS3cG in equilibrium, unless otherwise noted. Note that the combined
190OS4cG intensities are listed for {+190}Re isomer |b{+-} decay in 1974Ya02
190OS5cG but are actually for the combination of two activities, with the ground
190OS6cG state fed by the IT decays of {+190}Re isomer in equilibrium. The
190OS7cG combined intensities are given under comments for transitions seen in
190OS8cG both activities. The unplaced |g rays belong to {+190}Re (3.0 min)
190OS9cG and/or {+190}Re (3.1 h). The decomposition of the combined intensities
190OSacG is based on that 2352, 1996 and 1387 levels are the only levels fed
190OSbcG directly by the |b{+-} decay of the 3.0-min g.s. but not by the |b{+-}
190OSccG decay of the 3.1-h isomer and the 2352 and 1996 levels are not
190OSdcG populated in the |b{+-} decay of the 3.1-h isomer, as claimed by
190OSecG 1974Ya02, and it is performed from higher levels to lower levels.
190OSfcG Intensity values in 1974Ya02 are relative to combined I(371.2|g)=100.
190OSgcG Values are also reported by 1969Ha44 for intense transitions only,
190OShcG relative to I(224|g)=100, and they agree well with the values given
190OSicG here after being renormalized to I(224|g)=59.0 {I24} here, as given
190OSjcG under comments.
190OS cG E(F),RI(F)$|g ray reported in {+190}Ir |e decay (12 d) (1974Ya02). I|g
190OS2cG deduced from branching ratios in {+190}Ir |e decay and I|g value of
190OS3cG the strongest branch from the parent level in this decay.
190OS cG RI(A)$From intensity balance at 187 level. This value agrees with
190OS2cG 140 {I19} from 1969Ha44, but disagrees with 170 {I23} obtained from
190OS3cG 310 {I22} (1974Ya02) combined for 3.1-h {+190}Re and 3.1-min {+190}Re
190OS4cG in equilibrium and 140 {I7} for 3.1-h {+190}Re. The combined intensity
190OS5cG of 310 {I22} from 1974Ya02 is probably in error since it implies
190OS6cG |b{+-} feeding of |?28% to 187 level in this decay, too high to be
190OS7cG explained by the |b{+-} spectrum given by 1969Ha44 which essentially
190OS8cG indicates only one |b{+-} group (to 1387 level). The 1387 level is
190OS9cG claimed to be the only level that is strongly fed in this decay also
190OSacG by 1974Ya02
190OS cG RI(G)$Corrected for I(|g+ce from 558 level) equal to the total I(|g+ce)
190OS2cG of 198.1|g, 397.4|g, 605.1|g, 829.0|g, 1437.5|g, and 1794.5|g that feed
190OS3cG the 756 level in this decay in decomposition of combined intensities
190OS cG RI(E)$Corrected for I(|g+ce from 756 level) equal to the total I(|g+ce)
190OS2cG of 199.3|g, 407.2|g, 630.9|g, and 1596.4|g that feed the 756 level in
190OS3cG this decay in decomposition of combined intensities
190OS cG RI(B)$Corrected for I(|g+ce from 955 level) equal to the total I(|g+ce)
190OS2cG of 207.9|g, 431.6|g, and 1397.1|g that feed the 955 level in this decay
190OS3cG in decomposition of combined intensities
190OS cG RI(C)$Corrected for I(|g+ce from 1163 level)=I(|g+ce)(223.8|g) in
190OS2cG this decay in decomposition of combined intensities
190OS cG RI(D)$Corrected for a 4.6% {I4} contribution from the decay of the
190OS2cG 3.1-h {+190}Re isomer in decomposition of combined intensities, which
190OS3cG is from a total I(|g+ce)=10.6 {I7} of 197|g, 295|g and 485|g to
190OS4cG 1387 level from higher levels only populated in that decay.
190OS5cG See {+190}Re |b{+-} decay (3.1 h) for I|g values for those |g rays. The
190OS6cG total I(|g+ce) of |g transitions from 1387 level for combined
190OS7cG activities is 232 {I9}.

190OS cN NR$From |S[I(|g+ce) from 1387, 1996, 2352 levels]=100. The |b{+-}
190OS2cN spectrum and |g-ray data (1969Ha44) from the 3.0-min activity alone
190OS3cN (no apparent presence of 3.1-h {+190}Re) suggest no |b{+-} feeding to
190OS4cN levels below 1387. Unplaced |g rays, listed in {+190}Re |b{+-}
190OS5cN decay (3.1 h), are not expected to affect the normalization factor
190OS6cN since most of these deexcite levels above 187. See also comments with
190OS7cN {+190}Re |b{+-} decay (3.1 h)
