General Comments:

84Nb nuclide evaluated by d. Abriola and M. Galan

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

Q-value: ΔQ(β-)=500, ΔS(n)=420, ΔS(p)=ΔQ(α)=300 (2009AuZZ).

Q-value: Q(εp)=3700 300 (syst,2009AuZZ).

Q-value: The values in 2003Au03 are: Q(β-)=-6070 500, S(n)=10990 430, S(p)=2710 310, Q(α)=-3090 350, Q(εp)=3160 300; all from systematics
