149HO c 1988To13 (also 1991To12,1989Ko02): {+153}Tm ions were produced with
149HO2c {+92}Mo({+64}Zn,3p) reaction with E=267 MeV (center of target) {+64}Zn
149HO3c beam from the Lawrence Berkeley Laboratory SuperHILAC on 93.37%
149HO4c enriched {+92}Mo foil target, followed by mass separation with the
149HO5c OASIS online facility, and collected in a moving table to a counting
149HO6c station. Charged particles were detected with a Si |DE-E telescope and
149HO7c a plastic scintillator; |g rays were detected with Ge detectors.
149HO8c Measured E|g, I|g, E(|a), I(|a), |a|g-coin. Deduced levels.

149HO c 1996Pa01: measured E|a.

149HO cA IA$From 1988To13. I|a(4586)/I|a(5109+5096)=4.5|*10{+-5} {I5},
149HO2cA I|a(4902)/I|a(5109+5096)=1.8|*10{+-5} {I4} (1988To13)
149HO cA E(B)$1988To13 suggest that this peak is a doublet, with
149HO2cA components from both the 1.48- and 2.5-s isomers; although
149HO3cA transitions from 2.5-s, (1/2+) parent would be favored in view of
149HO4cA low L value involved rather than much higher L value implied
149HO5cA by the 1.48-s, (11/2-) parent.
149HO cA HF$The nuclear radius parameter r{-0}({+149}Ho)=1.5621 {I20}
149HO2cA is deduced from interpolation (or unweighted average) of radius
149HO3cA parameters of the adjacent even-even nuclides in 2020Si16
149HO cG E$From 1988To13. The |g rays are from the decay of either one of the
149HO2cG activities of {+153}Tm or both. However, (1/2+) parent would be
149HO3cG favored in view of low L value involved rather than much higher L
149HO4cG value implied by the 1.48-s, (11/2-) parent.
