92Y H TYP=FUL$AUT=CORAL M. BAGLIN$CIT=NDS 113, 2187 (2012)$CUT=15-Sep-2012$
92Y C OTHERS: 1956HE77, 1957HE39, 1979BO26, 1990RU05.
92Y CB 1957HE39 observed no BG coin for EB>600 KEV.
92Y CB E(D) Weighted average of 536 20 (1983IA02) and 546 30
92Y 2CB (1978WO15, from |b-1384|g coincidence spectrum). Q(|b{+-})=1951 9
92Y 3CB (2011AUZZ) implies EB=567 9. Others: 545 KEV 50 (1957HE39), 550 KEV 50
92Y 4CB (1956HE77).
92Y CG Measured: G-ray singles with Ge(Li) (1972OL03,1971PA31),
92Y 2CG coincidences with Ge(Li)-Ge(Li) (1972OL03), Ge(Li)-NaI (1971PA31).
92Y 3CG EG and IG from both sources are in excellent agreement.
92Y CG Measured average EG=1130 80 (1990RU05) cf. 1337 19
92Y 2CG CALCULATED FOR THE ADOPTED DECAY SCHEME USING THE CODE ^RADLST.
92Y CG E,RI Weighted average of data from 1972OL03 and 1971PA31.
92Y 2CG An additional, weak line (EG=463.4 2, IG=0.04 1) reported in
92Y 3CG 1971PA31 was not confirmed by 1972OL03 (IG LE 0.015); evaluator does
92Y 4CG not adopt this G.
92Y CG E(B) Weighted average of data from 1972OL03, 1971PA31, 1979BO26.
92Y CG E(F) Note comment on 430 level regarding order of 430G-953G
92Y 2CG cascade.
92Y CL The decay scheme is based on G-ray singles and
92Y 2CL coincidence measurements by 1972OL03 and 1971PA31.
92Y CL E From least-squares fit to EG.
92Y CL J,T From Adopted Levels.
92Y CL E(E) The order of the 430G, 953G cascade is not established in
92Y 2CL 92SR B- decay data. Consequently, a level exists at either
92Y 3CL 430.56 5 or 953.31 7, and the authors chose the latter. 1956HE77
92Y 4CL reported EB=1500 100, which would support the 430-level option;
92Y 5CL however, 1957HE39 observed no BG coincidences for EB>600 KEV. The
92Y 6CL decay scheme implies negligible B- feeding
92Y 7CL of either state since I(430G) and
92Y 8CL I(953G) are similar. (D,A) excites a (2,3,4)- level at 440 KEV 30.
92Y 9CL The evaluator presumes that this confirms the 430-level option, and
92Y ACL has ordered the 430G and 953G accordingly.

92Y CN NR from |S(TI to GS)=96% 4, derived assuming
92Y 2CN LOGF1UT>8.5 TO GS (which implies IB(GS)<8%). This is consistent
92Y 3CN with IG normalization=0.90 10 based on measured I(1384G)=90% 10
92Y 4CN (1957HE39) obtained from comparison of |b-decay rate (4|p flow
92Y 5CN proportional counter) with emission rate of 92Y(1384G). If no B-
92Y 6CN branch existed to GS, |S(TI to GS)=100% would imply IG
92Y 7CN normalization=0.93 3, with no
92Y 8CN significant change in deduced LOGFT values. IG normalization
92Y 9CN does not depend on the order of the 430G-953G cascade.
