149GD c Q value measurements: 1991Ke06 and 1985Sc09. From |b{++}|g coin,
149GD2c E(|b{++})=1853 {I10} (1991Ke06) which gives Q=3671 {I10}. 1985Sc09
149GD3c estimate Q value from I(|b{++})/I(|eK(exp)) and I(|b{++})/I(|e+|b{++})
149GD4c ratios deduced from |g{+|+}/I(x ray) and |g{+|+}/I|g(cascades). From
149GD5c I(|b{++})/I(|eK(exp))=0.31 {I3}, 1985Sc09 deduce E|b+=1790 {I50} which
149GDxc gives Q=3610 {I50}
149GD c Total decay energy deposit of 3986.6 keV {I34} calculated by RADLIST
149GD2c code is higher than the expected value of 3673 keV {I4}, with a

149GD2cN approximately 100% decay to 796 level since other unassigned
149GD3cN transitions are not intense enough to change the feeding to this

149GD3cG is most likely due to missing feeding transitions to the 165 level
