229PA cP T$From {+229}Pa Adopted Levels in the ENSDF database, where the value
229PA2cP is adopted from the measurement by 1987Ah05. A recent measurement by
229PA3cP 2018Gr09 reports T{-1/2}=1.55 d {I1} (weighted average of the following
229PA4cP eight values deduced from decay curves for 117.2- and 119.0-keV |g rays
229PA5cP at four different proton bombarding energies: 1.83 d {I5}, 1.49 d {I2},
229PA6cP 2.08 d {I6}, 1.60 d {I2}, 1.66 d {I5}, 1.47 d {I2}, 1.78 d {I10},
229PA7cP 1.43 d {I3}). Evaluator's analysis of this result: eight values from
229PA8cP 2018Gr09 form a discrepant dataset, as regular weighted average gives
229PA9cP 1.55 d {I5} (not an uncertainty of 0.01 d as given in 2018Gr09), but
229PAAcP reduced |h{+2} of 24 is very large in comparison to critical |h{+2}=2.1
229PABcP at 95% confidence level. Weighted average by the method of limitation
229PACcP of relative statistical weights (LRSW) method gives 1.53 d {I5}, but
229PADcP still with reduced |h{+2}=14, and rejecting the 2.08 d {I6} value as an
229PAEcP outlier. Weighted average by Normalized Residuals method (NRM), which
229PAFcP adjusts uncertainties in data points considered as outliers, gives
229PAGcP 1.50 d {I3}, with reduced |h{+2}=5, still too large to be acceptable.
229PAHcP It would seem that unweighted average, which gives a value of
229PAIcP 1.67 d {I8} is perhaps an appropriate way to deal with this dataset.
229PAJcP Based on above problematic issues with these data, reported T{-1/2}
229PAKcP from 2018Gr09 is omitted in the adopted half-life of {+229}Pa decay.
