Abstract: | Based on combination of the two-step collinear isotope-selective photoionization and time-of-flight separation of atoms in a fast modulated beam, a new technique has been developed for detecting the3He rare isotope with an isotopic selectivity of up to 1010. The technique helped to detect optically, for the first time,3He at a relative abundance of 4·10–8. |
