156TB D DATA SET UPDATED (FEBRUARY, 2012) BY CW REICH TO INCLUDE NEW CC VALUES
156TB c Data are from 1957Mi01, 1957Mi67, and 1970To11 for the |g ray and
156TB2c 1950Wi13, 1955Ha52, and 1970To11 for the half-life. Others: 1970Ag02;
156TB3c 1975ViZP.
156TB c Experimental methods:
156TB c 1950Wi13: from {+153}Eu(|a,n), E(|a)=19-38~MeV and Gd(p,xn),
156TB2c E(p)=10~MeV. |b{++} observed in spectrograph.
156TB c 1955Ha52: from (p,xn) on enriched Gd targets with chemical separation.
156TB2c Half-life measured.
156TB c 1957Mi01: From (p,xn) with chemical separation. ce measured using
156TB2c magnetic spectrometer. Report 88-keV G.
156TB c 1957Mi67: From (p,xn) with chemical separation. ce measured using
156TB2c magnetic spectrograph. Report 88-keV G.
156TB c 1970To11: From {+157}Gd(p,2n) on enriched (93.7%) and natural (15.6%)
156TB2c targets with chemical separation. ce measured using magnetic
156TB3c spectrometer. Report half-life and multipolarity of 88-keV G.
156TB D OTHER:
156TB D 1975ViZP: Produced by irradiation of GD target with chemical separation
156TB2D GG and XG coincidences measured.
156TB cG M From {+156}Tb Adopted |g radiations.
156TB cL J From {+156}Tb Adopted Levels.
156TB CL BAND(A)$K{+|p}=3- Bandhead, conf=|p3/2[411]+|n3/2[521].
156TB CL BAND(D)$K{+|p}=0+ Bandhead, conf=|p3/2[411]-|n3/2[402].

156TB N 0.0115 LT 0.0115 LT 1.0
156TB PN 2
156TB cN NR,NT evaluator assumes that 100% of the IT decays are through the
156TB2cN 88-keV |g transition. Thus, this value represents an upper limit.
156TB cN BR value unknown, but 1950Wi13 and 1970Ag02 report |b{++} decay.
156TB L 0.0 3- 5.35 D 10 A
156TB cL T$From Adopted Levels.
156TB L 88.4 (0+) 5.3 H 2 DM
156TB2 L %IT<100 $ %EC+%B+>0
156TB cL T From Adopted Levels and based on data of 1950Wi13, 1955Ha52,
156TB2cL and 1970To11.
156TB cL %IT Value unknown, but it is <100, since |b{++} decay has been
156TB2cL reported (1950Wi13,1970Ag02). 1950Wi13 report E|b+|?1400 which agrees
156TB3cL with Q value of 2544 {I4}, but their limit of I|b{++}<25% is not
156TB4cL useful since I|e/I|b{++}>7 already requires I|b{++}<13%. 1970Ag02
156TB5cL report E|b+=2640.0 {I5}, which is much too high, so their value
156TB6cL of I|b{++}=0.024% {I8} may also be in error.
