190RE c 1974Ya02 (also 1974YaZU): {+190}Re ions were produced by the (d,|a)
190RE2c reaction with natural osmium bombarded with a 18 MeV deuteron
190RE3c beam from the ANL 152-cm cyclotron. |g rays were detected with Ge(Li)
190RE4c detectors. Measured E|g, I|g, |g|g-coin, |g(t). Deduced T{-1/2} of
190RE5c g.s. and isomer. See more data for {+190}Os in {+190}Re |b{+-} decay.
190RE c 2012Re19: direct measurement of the masses of ground state and isomer
190RE2c of {+190}Re by Schottky mass spectrometry technique.
190RE3c {+190}Re produced in {+9}Be({+197}Au,X),E=478-492 MeV/nucleon reaction
190RE4c using UNILAC-SIS facility at GSI. Target was {+9}Be 1035 mg/cm{+2} with
190RE5c a 221 mg/cm{+2} niobium backing. Mostly bare atoms
190RE6c of the highly-charged reaction products were separated with FRS and
190RE7c injected into storage ring ESR. The ions were stochastically and
190RE8c electron cooled. Deduced masses from Schottky spectra; identified
190RE9c high-spin isomer

190RE4cN number of {+190}Re g.s. decays is equal to the total number of {+190}Re

190RE6cN the relative |g intensities given as for {+190}Re isomer |b{+-} decay
190RE7cN in 1974Ya02 are actually for the combination of {+190}Re isomer and
190RE8cN g.s. |b{+-} decays, with the latter fed by the IT decays of {+190}Re
190RE9cN isomer in equilibrium. See those decay datasets of {+190}Os for more
190REacN details.

190RE cL T$the adopted value is from weighted average of 3.3 h {I2} (1974Ya02),
190RE2cL 3.0 h {I5} (1972Ru06), and 2.96 h {I20} (1973DeWI). The original
190RE3cL uncertainty of 0.10 in 1973DeWI seems too small (probably statistical
190RE4cL only) and has been increased by a factor of 2 in the average by the
190RE5cL evaluators. Other: 2.8 h (1962Ba60)

190RE cG E$no isomeric transitions from the decay of this isomer have been

190RE3cG suggested by evaluators. If this transition has 100% I(|g+ce)
190RE4cG branching, then B(M3)(W.u.)=1.02|*10{-4} {I+12-11}. E4 transition to
190RE5cG the g.s., (2)- is also possible.
