| Abstract: | 72Se has been produced by bombarding a thick target of natural germanium with 38.4 MeV 24He ions. The target was allowed to decay for three days to remove 73Se. 72Se was separated as elemental selenium and mounted on a column of cationic exchange resin. When 72As had grown to equilibrium the column was warmed to 60°C and eluted with distilled water. Seventy per cent of the eluted arsenic was in the first three 5 ml fractions. No impurities could be detected in the gamma spectrum. The yield of 72As was at least 60%. |
