Q(β-)=4994 keV 19S(n)= 4235 keV 21S(p)= 7141 keV 21Q(α)= 2.5×103 keV SY
Reference: 2012WA38

General Comments:

Assignment: 238U(600-MeV p spallation) mass separation (1987Ku04).

230Fr was produced by fragmentation of 1 GeV 238U beam and identified by determining its magnetic rigidity, velocity, and atomic number (2010Al24).

230Fr was produced by bombardment of uranium or thorium targets with 1.0-1.4 GeV protons (2004Pe17)

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

Q-value: ΔQ(α)=504 (2011AuZZ).
