ABSTRACT:
Isotope separation, particularly separation of isotopes of lithium, is achieved by exposing a beam of atoms to radiation that selectively excites atoms of a particular isotope without exciting atoms of other isotopes of that element. The excited atoms are ionized by solar radiation and the ions attracted to an ion collector plate maintained at a negative potential. The atoms not ionized are condensed on a grounded atom collector plate. Optionally, the solar radiation not absorbed by the system may be used to generate electricity. Lithium isotopes are useful in nuclear reactors and nuclear weapons.
