153HO c Produced by {+142}Nd({+16}O,5n) with E |< 138 MeV and measured |g
153HO2c singles, |g|g coincidences, and |g(t).
153HO c Data here are from 1994Xu09 and 1996Xu03.
153HO cE TI From 1996Xu03 and based on intensity balances. Since the
153HO2cE decay energy is 4.5 MeV and levels are reported only to 1.8 MeV,
153HO3cE the decay scheme is incomplete and these values may not be
153HO4cE very accurate. For example, the log{Ift} of 5.9 for the unique
153HO5cE first forbidden decay from (7/2-) to (3/2+) is too low. As the
153HO6cE |e feeding is moved to higher energy levels, these I(|e+|b{++})
153HO7cE will decrease and the log{Ift} values increase becoming lower
153HO7cE limits
153HO cE TI,LOGFT$The 2nd and 3rd forbidden decays to the ground state and
153HO2cE 68-keV level are assumed to be negligible. Uncertainties are
153HO3cE not given because the scheme is assumed to be incomplete.
153HO DE TI Values are per 100 EC+B+ decays.
153HO cG E,RI From 1994Xu09, except for the two |g's that are only given
153HO2cG in 1996Xu03. The larger intensities given in 1996Xu03 for the
153HO3cG 188 and 377 |g's are assumed to include internal conversion.
153HO cG M(a)$Assumed in 1994Xu09 from |DJ{+|p}{-(levels)} and so to keep the
153HO2cG intensity balance of the coincidence relations.
153HO cL J$The J|p and configuration assignments are from 1996Xu03 and
153HO2cL are based on comparison with model calculations and systematics
153HO2cL of odd Ho isotopes. These are used
153HO3cL to suggest the nucleus is spherical in the ground state.

153HO2cN the ground state and 68-keV level, but the uncertainty is large
153HO3cN since the decay scheme is assumed to be very incomplete.

153HO cE TI,LOGFT$From the intensity balance one obtains I(|e+|b{++})
153HO2cE |< 4.7% of the |e+|b{++} decays and log{If{-1u}t} |> 7.5. But, from
153HO3cE log{Ift} systematics (1998Si17) the log{If{-1u}t} is expected to be
153HO4cE |> 8.5 which corresponds to I(|e+|b{++}) |< 0.5% of the |e+|b{++}
153HO4cE decays.

153HO cG RI This value is given in 1994Xu09 and 1996Xu03 as 1.5 {I10},
153HO2cG but this value is too large. For its minimum (1 |s) value
153HO3cG of 0.5 and the minimum |a(M2)=30.7, its minimum I(|g+ce) is 16;
153HO4cG this gives a feeding of the 256 level of 55 units plus the
153HO5cG I(|e+|b{++}) feeding and a depopulation of only 49 units. If
153HO6cG there is a significant E3 component with |a=68.8, this
153HO7cG discrepancy becomes quite large. 1994Xu09 and 1996Xu03 show
153HO8cG |? 5% of the |e+|b{++} decay to the 256-keV level, which
153HO9cG suggests I|g=0.15, and this value is used here.
