181PT c  1976GrZC: Source prepared in ISOLDE II at CERN; Ge detector
181PT2c  for X-ray and |g's; surface barrier detector for |a's;
181PT3c  measured E|a, I|a, |a|g-coin.
181PT c  Others: 1953Ra02, 1963Ka17, 1968De01, 1970Ha18, 1978Ha30, 1970Ma24,
181PT2c  1977Ij01, 1979Ha10, 1980ToZZ, 2002An15.
181PT c  The level scheme has been analyzed by evaluator on the basis
181PT2c  of the systematics of the 1/2[521] rotational band, and on reported
181PT3c  coincidence data.
181PT cL E         Based on E|g.
181PT cL J         From adopted levels.
181PT cG E         From 1976GrZC; uncertainty unstated by authors, but E|g
181PT2cG values match rounded-off values from the Adopted Gammas data set.
181PT cG M         From adopted gammas.
181PT cA IA        Deduced by evaluator from I|a(g.s.)/I|a(94)=24 {I2}
181PT2cA (1970Ha18). Other data: 25 (1976GrZC); I|a(g.s.):I|a(94)=96 {I1}:4
181PT3cA {I1} (1980ToZZ). |DI|a=0.3 was calculated by evaluator using the
181PT4cA error-propagation method of 1988Br07 and the constraint that
181PTxcA I|a(g.s.)+I|a(94)=100
181PT cA HF        If r{-0}=1.508 (based on r{-0}({+180}Pt) and r{-0}({+182}Pt)
181PT2cA from 1998Ak04).
181PT cL E(A)      The expected energy pattern for the 1/2[521] rotational band
181PT2cL is for the 3/2- and 5/2- members to lie close together, significantly
181PT3cL above the 1/2- bandhead, decoupling parameter a=+0.79;
181PT4cL thus, the 15-keV 3/2- level option proposed by 1976GrZC seems unlikely.

181PT cN BR        0.055 {I7} (1970Ha18) from absolute |a, K x ray, and
181PT2cN |g{+|+} counting. No correction for internal conversion electrons
181PT3cN was made, which may have increased this value. However, an upper
181PT4cN limit of 0.07 can be set by requiring HF|>1 for the 5653|a.
181PT5cN Branching was not corrected for a possible contribution to the K x-ray
181PT6cN intensity due to 46% |e decay from {+185}Hg(21 s) reported by 1982Bo27.
181PT7cN The evaluator adopts %|a=6 {I1}.
