Laser detection of the rare isotope (3)He at concentrations as low as 10(-9)
Abstract:
The method of collinear laser photoionization of atoms in a modulated fast beam is used to detect the rare isotope (3)He, with high-repetition-rate lasers being applied to improve the detection sensitivity. The method has made it possible to detect (3)He at relative abundances as low as 10(-9).
