General Comments:

1998Pf02: 220Po nuclide identified in 9Be(238U,X) reaction at E(238U)=1 GeV/nucleon at GSI, FRS separator used to separate fragments of 238U beam

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

Q-value: ΔQ(β-)=207, ΔS(n)=283 (syst,2009AuZZ);

Q-value: Q(β-)=1110 ΔQ(β-)=360 (syst. 2003Au03) S(n)=5410 ΔS(n)=510 (syst. 2003Au03)
