186PB c Others: 2001An07, 1999An22, 1997An09, 1988QuZZ.
186PB c 2001An07, 2000An14; {+190}Po source from {+142}Nd({+52}Cr,4n),
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 c T{-1/2}({+190}Po)=2.45 ms {I5} weighted average of 2.45 ms {I5}
186PB2c 2000An14 and 2001An07, 2.5 ms {I3} (1999An22), and 2.5 ms {I1}
186PB3c (2003Va05), 2.0 ms {I+5-10} (1997Ba25),
186PB4c 1.9 ms {I+6-4} (1997An09), 2.0 ms {I+5-10} (1996Ba35).
186PB5c Other: 10 ms {I+47-4} (1988QuZZ) may not belong to {+190}Po.
186PB cA IA$from (2000An14,2001An07)
186PB cA HF r{-0}({+186}Pb)=1.512 {I3} for HF(to g.s.)=1.0.
186PB cG E,M$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.

186PB N 1.00
186PB cN BR based on calculated partial |e+|b{++} half-life of 6.67 s
186PB2cN (2019Mo01), %|a=99.99; therefore, %|a|?100 has been assumed.

186PB cA E Weighted average of 7533 {I10} (2000An14,2001An07) and
186PB2cA 7529 {I10} (1997Ba25) - assuming both supersede their earlier values -
186PB3cA 7545 {I15} (1999An22), 7550 {I15} (1997An09), 7490 {I40} (1996Ba35).
186PB4cA Other: 7482 {I20} (1988QuZZ - report two events).
