S(p)= 5.E2 keV SYQ(α)= -1.01×104 keV SY
Reference: 2012WA38

General Comments:

1996PoZZ: re-analysis of upper limits for T1/2 obtained at LISE (GANIL). Unstable to proton emission. No evidence was found for the existence of 34Ca

34Ca is a candidate for two-proton emission since S(2p) is negative

Structure calculations: 2002Zh09, 2001Yo12, 1998Co30

Two-proton decay calculations: 2004Pf02, 2003Gr04

Giant-resonances calculations: 2001Sa57, 1997Ha57

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

Q-value: ΔS(p)=357, ΔQ(α)=585 (2011AuZZ)

Q-value: Q(εp)=15947 298, S(2p)=-1474 298 (syst,2011AuZZ)

Q-value: Values in 2003Au03 (from syst): S(p)=900 360, Q(α)=-9360 420, Q(εp)=15250 300, S(2p)=-780 300
