  A  78Zn β- decay (1.47 S)  B  78Ga IT decay (< 500 NS)
  C  79Zn β-n decay (0.995 S) 

General Comments:

Mass measurement: 2008Ha23, 2007Gu09 (also 2005Gu36)

Production: 238U(p,F) E=25 MeV: 1977Hu09, 2002Kr13

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

Q-value: S(2n)=13552 3, S(2p)=27308 7 (2009AuZZ,2003Au03)

Q-value: Values in 2003Au03: S(p)=12270 120; others are within 1 keV of those in 2009AuZZ
