ABSTRACT:
A photochemical method for changing the isotopic composition of an element is disclosed. The method involves passing an electron discharge through a mixture of a buffer gas, which controls the uniformity and electron temperature of the discharge, and a vapor of the element. By means of the phenomenon of resonance radiation trapping, the electron discharge preferentially excites and ionizes one isotope. Removal of the ions by cataphoresis separates the element into two amounts with different isotopic ratios.
