25NA c Source produced by {+9}Be({+18}O,2p) E=44 MeV; Ge(Li) detector,
25NA2c NE102 scintillator. Measured E|g, I|g, |g-|b coincidence; deduced
25NA3c |b feeding, log {Ift}, {+25}Ne half-life, etc.
25NA cG RI$From 1973Go11.
25NA cG M,MR$From Adopted Gammas
25NA cL E$From a least-squares fit to E|g ignoring the calculated E|g
25NA cL T$From Adopted Levels
25NA cB IB$From intensity balance at each level, except where noted otherwise.
25NA2cB The values of 1973Go11 are listed in the comments.

25NA cN NR$authors report I|g per 100 decay in 1973Go11 (calculated
25NA2cN assuming |S(I|g) to the g.s.=100 and no |b feeding to the g.s.).
25NA3cN Note that in the abstract the same I|g's are mentioned as relative
25NA4cN intensity, in fact it is relative in absolute scale, i.e. per 100
25NA5cN decay.

25NA B
25NA cB IB$In 1973Go11, an upper limit of |<20 (at the 85% confidence level)
25NA2cB g.s. feeding was proposed based on their measured value of
25NA3cB |b{-0}/|b{-1}=0.17 {I9}. For a g.s. feeding of
25NA4cB I|b=10 {I10}, the log {Ift}=4.43 {I1} can be obtainted, which would
25NA5cB indicate an allowed transition, whereas for a 1/2{++} to 5/2{++}
25NA6cB non-unique 2nd forbidden |b transition log {Ift}|>10.95 (2023Tu02)
25NA7cB can be expected. Only a very small branch like I|b|<0.004 can
25NA8cB satisfy the log {Ift} limit. The evaluator assumes a "zero" g.s.
25NA9cB |b feeding.
