General Comments:

84Ge evaluated by α.α. Sonzogni, M. Fadil, and B. Pfeiffer

Precise atomic mass measurement: 2008Ha23 (Penning-trap system). Other mass measurement: 2006Ha62

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

Q-value: Q(β-n)=3450 4 (2009AuZZ).

Q-value: The values in 2003Au03 are: Q(β-)=7840 420, S(n)=5420 360, S(p)=16150 420, Q(α)=-8830 340, Q(β-n)=3560 370; all from systematics
