S(n)= 1.43×104 keV SYS(p)= 8.E2 keV SYQ(α)= -1.9×103 keV SY
Reference: 2012WA38

General Comments:

Q(εp)=1.41×104 6 (syst; 2011AuZZ)

2011RoZZ: 65Se produced in the fragmentation of 78Kr on a Ni target with E(78Kr)=70 MeV/nucleon. Fragments selected with the α-LISE3 separator and identified by ToF and ΔE. Measured Ep, Eβ, Eγ, T1/2 using DSSD detector surrounded by 4 HPGe Clover detectors.

1995Hu24: 65Se produced in the 40Ca(28Si,3n) reaction and observed through delayed proton emission.

1993Ba12: The Tz=-3/2 (α=4n+1) nuclide 65Se was produced in 40Ca(28Si,3n), E=175 MeV 28Si (6+) beam, and observed by its delayed proton emission. Similar previous efforts by 1987Ho01, 1978ViZT were unsuccessful.

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

Q-value: ΔS(p)=7×102 syst (2011AuZZ); ΔQ(α)=7×102 syst (2011AuZZ)

2011RoZZ observed 3.51 MeV 2 proton decay from 3.4 MeV 9 IAS in 65As. %β+=48 15 to the IAS. Authors assumed superallowed transition to IAS with log ft=3.57 20. These results are consistent with those of 1993Ba12.
