190RE c  1976Ha39: sources of {+190}W were produced via the (n,2pn) and (p,3p)
190RE2c  reactions by the irradiation of isotopically enriched (98%) {+192}O
190RE3c  metal with E=25-200 MeV neutrons from the MEIN facility at BNL and E=92
190RE4c  MeV protons from the Brookhaven Linac injector of the alternating
190RE5c  gradient synchrotron (AGS). |g rays were detected with a 50-cm{+3}
190RE6c  Ge(Li) detector and |b particles were detected with a plastic
190RE7c  scintillator. Measured E|g, I|g, |b, |b|g-coin, x-ray. Deduced
190RE8c  levels, J, |p, parent T{-1/2}, configurations, log {Ift}, |g-ray
190RE9c  multipolarities. Comparisons with theoretical calculations.
190RE cG E,RI$From 1976Ha39
190RE cG M$Proposed by 1976Ha39 from intensity balance, assuming 157|g and 162|g
190RE2cG are in a cascade. However, deduced I(K vacancies)=118 {I12} disagrees
190RE3cG with measured value of 77 {I7} (1976Ha39)
190RE cL E$Based on observed (950|b)(157|g) coin. The 157|g-162|g cascade is
190RE2cL based on intensity balance with known |g rays from 3.1-min {+190}Re
190RE3cL decay in equilibrium. Also Q(|b{+-}) deduced from the proposed cascade
190RE4cL agrees well with that deduced from mass calculations
