Q(β-)=6821 keV 7S(n)= 5857 keV 9S(p)= 10486 keV 11Q(α)= -5932 keV 11
Reference: 2012WA38

References:
  A  97Sr β- decay  B  97Y IT decay (1.17 S)
  C  97Y IT decay (142 MS)  D  98Sr β-n decay (0.653 S)

General Comments:

Searched for p radioactivity, not found (1989Ho19). Search range 250 keV|<E|<600 keV, 10 μs|<T1/2|<100 ms.

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

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)
