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)
