235PA D New Q- values are from 2012Wa38. New log ft's. (Modified 12/3/2013).
235PA C 1986Mi10: Source prepared by irradiating natural ^U with 30-160 MEV,
235PA2C 14-MEV n; chem, measured G, B, G(T); GELI, PC.
235PA c Analogy with {+233}Th and {+237}U |b{+-} decays suggests that the main
235PA2c |b{+-} branches feed the (3/2-) g.s. and (1/2-) first excited state in
235PA3c {+235}Pa. This suggestion has been confirmed by the low experimental
235PA4c absolute |g-ray intensities (I|g normalization|?0.02 from 1986Mi10 and
235PA5c 1989Yu01). However, the experimental |b{+-} endpoint of 1440 {I50}
235PA6c (1989Yu01) together with Q(|b{+-})=1729 {I19} (2012Wa38) (mass
235PA7c adjustment) suggests that there is a significant |b{+-} feeding to a
235PA8c level at about 290 keV. This discrepancy has not been resolved.
235PA cB IB$Intensities are approximate. They have been deduced from |g-ray
235PA2cB photon intensity balances without including conversion electrons.

235PA cB E$E|b=1440 {I50} from 1989Yu01 (abstract and fig. 3; the value 1400 in
235PA2cB the text is probably incorrect. The value Q(|b{+-})=1470 keV 80, also
235PA3cB given in 1989Yu01, assumes that the main |b{+-} branch feeds the
235PA4cB 1/2[400] rotational band, which is unexpected from systematics).
235PA5CB This value of E|b is inconsistent with Q(|b{+-})=1729 KEV 19
