Abstract
A method for extracting silicon isotopes was developed. Polycrystalline 28Si, 29Si, and 30Si samples isotopically enriched to 99.95, 99.5, and 99.9%, respectively, were prepared. Energies of optical phonons in the isotopically pure samples show the expected dependence on the average atomic mass.
