Isotopic Abundance Determination of Copper by Sputtering

Isotopic Abundance Determination of Copper by Sputtering

A spectrometer is described, in which an energy-resolved Cs ion beam sputters a Cu target at an incident energy of 0.3 to 3 kev. The sputtered Cu ions are then accelerated into a second part of the spectrometer, in which the Cu/ sup 63/ and Cu/sup 65/ components are separated completely. The complet...

Zusammenfassung:A spectrometer is described, in which an energy-resolved Cs ion beam sputters a Cu target at an incident energy of 0.3 to 3 kev. The sputtered Cu ions are then accelerated into a second part of the spectrometer, in which the Cu/ sup 63/ and Cu/sup 65/ components are separated completely. The completeness of this separation indicates that the energy spread of the sputtered ions is less than 10 ev. The Cu/sup 63//Cu/sup 65/ isotopic ratio is found by this method to be 2.25 plus or minus 0.02. (T.F.H.)
