184HG C  1993WA03: MASS-SEPARATED 188PB SOURCE FROM 155GD(40AR,7N), E=240 MEV;
184HG2C  ^PIPS-type |a DETECTORS (FWHM=23 KEV AT 5486), PLASTIC SCIN (FOR ce),
184HG3C  LOW-ENERGY Ge DETECTOR (FWHM=0.67 AT 122 KEV); MEASURED EA, IA, EG,
184HG4C  |a-X(t), |a-ce(t).
184HG C  The measured half-lives are ^T{-1/2}=23.6 S 45 (1972Ga27),
184HG2C  24.5 S 15 (1973Ho01), 26 S 2 (1974Le02), 22 S 2 (1984To09),
184HG3C  25.5 S 1 (1992Wa14). The weighted average of these values IS 25.1 S 1.
184HG4C  ^T{-1/2}(188PB)=24 S 2 was adopted by 1998Ak04 (unweighted average
184HG5C  covering all measured values), and used for that calculation of R0
184HG6C  (=1.491 14).
184HG C
184HG C  %A(188PB)=9.3 8 from 1999An22 is adopted here.
184HG2C  1998Ak04 adopted 8.5 13 from 1996Bi17.  Previously,
184HG3C  |a branchings of 15% and 22% 7 were deduced by 1981To02
184HG4C  from x-ray/|a and |g/|a counts, respectively; %|a=3-10 is
184HG5C  listed in 1992Wa14.

184HG C  QA(188PB)=6109 3 (2003AU03, 2009AUZZ).
184HG2C  EA(to GS)=5983 4 (1991RY01) gives QA=6113 4.
184HG CA E         |a energies to excited states were measured by 1993Wa03.
184HG CA IA        |a intensity per 100 |a decays.
184HG CA HF        R0(184HG)=1.494 4 is calculated by requiring the
184HG2CA hindrance factor for the 5983A to be 1.0.
