184AU D PARENT T: 30.6 S 3 (1972Fi12), 30.9 S 3 (1994Wa23).
184AU2D 32.5 S 10 (1970Ha18); from 5535A(T). 32.0 S 10 (1969Ha03).
184AU3D WEIGHTED AVERAGE: 30.87 S 26.
184AU c Others: 1975Ho03, 1971Hu02, 1969Ha03 (observed 157|g and 237|g).
184AU c 2005Sa40: mass-separated {+184}Hg source from fragmentation of molten
184AU2c Pb target by 600 MeV or 1 GeV protons; Ge(Li) and Si(Li) detectors,
184AU3c high resolution 180|' magnetic spectrograph; measured E|g, I|g,
184AU4c E(ce), I(ce). Additional sources from {+148}Sm({+40}Ar,X); planar Ge
184AU5c (FWHM=0.9 keV at 122 keV) for E|g|<1 MeV; two HPGe detectors (FWHM
184AU6c |?2.3 keV at 1.3 MeV) for E|g|<1.3 MeV; measured x-|g-t and |g-|g-t
184AU7c events which were sorted to provide prompt-, total- and delayed-
184AU8c coincidence bidimensional matrices (60 ns or 100 ns time windows).
184AU2c Supersedes 2003IbZZ; see also 1994Ib01.
184AU c 1994Ib01: mass separated source from bombardment of {+148}Sm by 185 MeV
184AU2c {+40}Ar ions; He-jet transport, iodine aerosol; two HPGe coaxial
184AU3c detectors, one HPGe x-ray detector; measured singles |g and x-ray
184AU4c spectra, |g|g(t), x-|g(t). See also 1994RoZY.
184AU c 1975Ho03: |b strength function deduced from total-absorption |g
184AU2c measurement
184AU c 1978Ne10: Mass-separated source; measured E|g, I|g, |g|g coin, |g|g(t)
184AU2c (time resolution 6 ns {I1}).
184AU c
184AU c The decay scheme is adopted from 2005Sa40. It differs greatly from
184AU2c that proposed by 1978Ne10. Although E|g and I|g data from 2005Sa40 and
184AU3c 1978Ne10 are in satisfactory agreement, there exist a number of
184AU4c transitions with E|g<90 keV which 1978Ne10 could not detect. Also,
184AU5c the lowest energy state reported in 1978Ne10 is actually a 68-keV 2+
184AU6c isomer, not a 3+ g.s., and the presence of a state just 3.4 keV above
184AU7c the isomer was not recognized by 1978Ne10.
184AU cE TI,LOGFT I(|g+ce) is from intensity imbalance at each level. I(|g+ce)
184AU2cE values <10% may not be reliable due to existence of unplaced
184AU3cE transitions, several of which are highly converted
184AUxcE (I(|g+ce)(30.3|g)|?6%).
184AU cG E,RI From 2005Sa40, except as noted.
184AU cG M From |a(K)exp values given by 2005Sa40, except as noted.
184AU cG MR From analysis of ce data by 2005Sa40.
184AU cG E(B) From 1978Ne10.
184AU cL E From least-squares fit to E|g.
184AU cL J From Adopted Levels.
184AU cL T From |g|g(t) (1978Ne10), except where noted.
