摘要：Method and apparatus for determining small quantities of specific atoms withisotopic selectivity. According to the method described herein, atoms are rapidly
released from an atom bank containing the same, and are then converted to ions utilizingresonance ionization as achieved with photon beams having specific wave lengths. Theseions are extracted from the ionization region and are accelerated and implanted into asecond atom bank. For further selectivity, the atoms are then rapidly released from thesecond bank, ionized with another photon beam of selected wave length to provideionization of the desired species, with these ions then being extracted, subjected toacceleration, and implanted into the first atom bank. Typically the number of electronsemitted from the atom banks during implantation is used as a measure of the number ofatoms of the selected species. In the preferred embodiments, a combination of massselectivity by ionization together with a mass separator provides for the most rapid andmost sensitive method for determining a small quantity of atoms in the presence of alarge quantity of atoms.
