156TB D  DATA SET MODIFIED (FEBRUARY, 2012) BY CW REICH TO CHANGE A CC VALUE
156TB2D   AND MODIFY THE Q VALUES.
156TB c  1970To11 produced this activity by the {+157}Gd(p,2n) reaction on
156TB2c  enriched (93.7%) and natural (15.6%) targets with chemical separation.
156TB3c  ce measured in magnetic spectrometer. One |g reported. Existence of
156TB4c  this activity confirmed by 1975ViZP.

156TB cN NR,BR$Since there is no evidence for the existence of an |e-decay
156TB2cN branch, the evaluator assumes that 100% of the decays are by isomeric
156TB3cN decay and that all of these are via the 49-keV |g.

156TB2 L  %IT=100
156TB cL %IT       Value assumed by evaluator since |b{+-} and |e decays have
156TB2cL not been reported.
156TB cL E         Level postulated to explain T{-1/2}. If T{-1/2} were
156TB2cL associated with the 49-keV level, E1 hindrance would be very large
156TB3cL (6|*10{+16}); and T{-1/2} of 49-keV level is known to be short
156TBxcL (1982Be46).
156TB cL T$From ce(t) for the 49.6 |g (1970To11).
156TB  G     X                 [E3]
156TB cG E         1975ViZP failed to see this |g in coincidence with the 49 |g
156TB2cG with two Si(Li) detectors.
156TB cG M$E3 is expected if this transition takes place between 7- and 4+
156TB2cG states, as proposed here.
