31P c 1980Wi13: {+31}S from {+31}P(p,n), 11 MeV protons from the ONR-CIT
31P 2c tandem accelerator. Target of MnP powder was bombarded then
31P 3c transferred to a counting station via a pneumatic shuttle (rabbit)
31P 4c system. Ge detectors used to measure E|g and I|g. Also 1980WiZQ thesis
31P c 1974Al03: {+31}S from {+31}P(p,n), 10 MeV protons from the Van de
31P 2c Graaff at Brookhaven. Rabbit transfer system from bombarding chamber
31P 3c to remote counting cell. Ge detectors used for E|g and I|g
31P xc measurements.
31P c 1971De05: {+31}S from {+31}P(p,n), 9-18 MeV protons from University of
31P 2c Colorado Nuclear Physics lab. Phosphorus target bombarded then
31P 3c transferred to a counting station via pneumatic shuttle system.
31P 4c Ge detectors used for |b-delayed |g-ray measurements but only reported
31P 5c |b-branching ratios.
31P c 2012Ba54: measured g.s. half-life of {+31}S
31P c Total energy deposit calculated by the RADLIST code is 5398.6 {I18},
31P 2c in a good agreement with Q-value=5398.01 {I23} (2021Wa16), indicating
31P 3c the completeness of the decay scheme.
31P cE TI$From intensity balance for excited states
31P cG E,M,MR$From Adopted Gammas. None of the papers cited above contain
31P 2cG independently measured |g-ray energies

31P N 0.01103 30 1 1
31P cN NR$From absolute intensity of 1266|g, obtained by comparing I(1266|g)
31P 2cN intensity with the positron-annihilation intensity. Adopted value is
31P 3cN weighted average of 0.01087 {I21} (1980Wi13), 0.0125 {I6} (1974Al03),
31P 4cN 0.011 {I1} (1960Ta14), 0.0098 {I20} (1977Az01).
