General Comments:

For shell-model calculations for levels in 92Y, see 1966Ve02 and 1973Wa36.

1974Su06 suggest principal configuration=((π 2p1/2)1(ν 2d5/2)3) for 310, 430, 780, 1030, 1310 levels, configuration=((π 1g9/2)(ν d5/2)3) for 1490, 1890 levels and configuration=((π 1g9/2)(ν d3/2)3) for 1690 level.

Q-value: Note: Current evaluation has used the following Q record

Q-value: Q(β-),S(n),S(p),Q(α): from 2011AuZZ; 3641 9, 6540 9, 8457 10, -4629 9, respectively, from 2003Au03.

E(level): Level energies with ΔE|<1 keV are from least-squares fit to Eγ from 92Sr β- decay; others are from (d,α).

   430.51(2)-   E(level): From 238U(82Se,Xγ). The order of the 430γ-953γ cascade is uncertain in 92Sr β- decay, allowing either a 430 level or a 953 level; the former is adopted because the (d,α) reaction indicates a level at 440 30 but no level near 953 keV.
