149DY c 1994Me13 (also 1989Me13): {+149}Ho ions were produced via
149DY2c fusion-evaporation reactions with 5.4 MeV/nucleon {+58}Ni beam on
149DY3c {+94}Mo and {+95}Mo targets at ISOLDE, GSI, separated by the GSI online
149DY4c separator and deposited on a transport tape. The |g- and x-rays were
149DY5c detected with a planar and two coaxial Ge(Li) detectors. Measured E|g,
149DY6c I|g, I(x-ray), |g|g-coin, |g(x-ray)-coin, |g(t). Deduced levels, J|p,
149DY7c parent T{-1/2}, conversion coefficients, |g-ray multipolarities, GT
149DY7c strengths. Comparisons with theoretical calculations. Configurations
149DY8c are suggested for all levels reported in this decay.
149DY c Other:
149DY c 1988ToZW: measured T{-1/2} of {+149}Ho isomer:
149DY c Total decay energy deposit of 6102 keV {I140} calculated by RADLIST
149DY2c code is in agreement with expected value of 6098 keV {I13}. However
149DY3c the decay scheme is considered as incomplete since a significant |b
149DY4c feedings may have missed detection in view of a large gap of about
149DY5c 3 MeV between Q(|e) value and the highest known populated level at 2938
149DY cE TI,LOGFT$I(|e+|b{++}) are from |g intensity balance at each
149DY2cE level. Most of the |b feedings should be treated as upper limits and
149DY3cE correspondingly, the log| {Ift} values as lower limits since the decay
149DY4cE scheme is considered incomplete by the evaluators. Exception is made
149DY5cE for |b feedings for the 1034.6, 1501.0, 2771.0 and 2788.6 level, where
149DY6cE feedings of |>10% can be realistic, and where uncertainties for
149DY7cE log| {Ift} values are given.

149DY cN NR$1994Me12 provide photon intensities per 1000 decays, with
149DY2cN statistical uncertainties as well as those from spectral complexity.
149DY3cN Evaluators divide I|g values in 1994Me12 by a factor of 10. Methodology
149DY4cN of measuring absolute |g intensities is not described in 1994Me13
