Levels: The configurations given in the table are from 97Y IT decay (142 ms) dataset
Gammas: All γ data are from 97Sr β- decay data set, unless otherwise noted (γ mult’s from conversion electron measurements)
Gammas: For unplaced γ’s see 97Sr β- decay and 97Y IT decay (142 ms) datasets
Q-value: Note: Current evaluation has used the following Q record $ 6689 11 5982 26 10608 29 -6065 14 2003Au03
Q-value: Q(β-n)=1114 11 (2003Au03); see also preliminary Penning-trap mass measurements, 2007Ha32 (97Y,96Y), 2006Ha03 (96Sr), and 2004Ri12 (96Zr), from which the following values are calculated: Q(β-)=6822 29 (a); S(n)=5855 11; S(p)=10488 9, Q(α)=-5931.9 11 (a), Q(β-n)=1214 41 (a, relative to daughter mass from 2003Au03)
