 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).

 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.
