General Comments:

Calculations: suppression of β+ decay: 1988Su04

Using total absorption spectroscopy, 2003NaZY study the Gamow-Teller transition. For decay of the 2- state, the Gamow-Teller strength is concentrated in a narrow prominent peak at about 4500 keV. For decay of the 9+ state, in addition to the peak at 4500, a second peak is seen at about 6100~keV

Q-value: Q(ε)=8780 5, S(2n)=21372 6, S(2p)=4350 6, Q(εp)=4610 5
