186PB2c  E=255 MeV; measured E|a, I|a, (|a)(ce) coin, |a-x coin, |a|g coin,
186PB3c  T{-1/2}({+190}Po); deduced triplet structure of 0+ states with
186PB4c  spherical, oblate and prolate shapes.  These two papers present data
186PB5c  from the same experimental measurement.

186PB cG E,M$Transition inferred from |a-ce coin data. Authors do not show
186PB2cG spectrum or give measured ce energy, but show transitions feeding g.s.
186PB3cG E0 multipolarity inferred by authors from observation of ce only.
186PB cL E$Deduced by evaluators using Q(|a)({+190}Pb) and adopted E|a values.
