156TB 156TB IT DECAY (24.4 H) 1970TO11 12NDS 201210
156TB H TYP=FUL$AUT=C. W. REICH$CIT=NDS 113, 2537 (2012)$CUT=1-Mar-2012$
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 cG M From {+156}Tb Adopted |g radiations.
156TB cL J From {+156}Tb Adopted Levels.
156TB cL BAND(A)$K{+|p}=3- Bandhead, conf=|p3/2[411]+|n3/2[521].
156TB cL BAND(B)$K{+|p}=4+ Bandhead, conf=|p3/2[411]-|n5/2[642].
156TB cL BAND(C)$K{+|p}=7- Bandhead, conf=|p3/2[411]+|n11/2[505].

156TB PN 2
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.
