91ZR3CN (1993HI09) in 91NB(60.86 D) decay, it follows that
91ZR4CN %IB+(to 91ZR GS)=0.0025 5, %(1205G)=2.02 8 and
91ZR5CN %(|e to 91ZR GS)=1.4 4, so %(105(|g+ce), 91NB)=(100-3.4 5).
91ZR6CN 1993HI09 have corrected their measured IB+ for a
91ZR7CN 6% {I2} contribution from 1205G pair production. (1993HI09 report
91ZR8CN slightly different branching because they assume CC(105)=174.)
91ZR9CN Note that RI(105G,91NB)/RI(1205)=0.286 16 from 1993HI09, cf. 0.233 9
91ZRACN (1986WA34), 0.164 (1955HA23).

91ZR CE IB 0.0025% 5 from 1993HI09; deduced from I(G+-) and I(XK, ZR)
91ZR2CE measured as a function of time for AP 590 days in order to
91ZR3CE differentiate between contributions from 91NB(60.86 D) and 91NB(680 Y)
91ZR4CE in source. The measured IB+ implies IE=2.7% 6 (cf. measured value of
91ZR5CE 1.4% 4) and LOGF1UT=9.45 9 based on first-forbidden unique theory.
91ZR CE IE measured value=1.4% 4 (1993HI09) (cf. 2.7% 6 expected based
91ZR2CE on theory and measured IB+); LOGF1UT=9.74 13 based on measured value.
91ZR CE LOGFT mean of values obtained based on measured IB+ and IE (9.45 9
91ZR2CE AND 9.74 13, RESPECTIVELY).
