149TB c 1974Sc19: source produced in {+147}Sm({+10}B,4n) reaction with E=53
149TB2c MeV beam from the Oak Ridge isochronous cyclotron (ORIC). Measured E|a,
149TB3c I|a, I(K|a x-ray), E|g, I|g. Deduced |a decay branching ratio.
149TB c Other measurements: 1971To01, 1978AfZZ, 1988To13
149TB c See also {+153}Ho |a decay (9.3 min)
149TB c 1964Ma10 have tentatively assigned a 27-min |a activity
149TB2c to {+153}Ho as a precursor of an observed 5-d activity assumed
149TB3c to be {+145}Eu. This assignment has not been adopted by the
149TB4c evaluators
149TB cA HF$The nuclear radius parameter r{-0}({+149}Tb)=1.565 {I11}
149TB2cA is deduced from interpolation (or unweighted average) of radius
149TB3cA parameters of the adjacent even-even nuclides in 2020Si16.
