Separation of osmium isotopes by dissociation of the OsO4 molecule in a two-frequency infrared laser field

A report is given of the separation of osmium isotopes by the method of selective dissociation of the OsO₄ molecule in a two-frequency infrared laser field. It is shown that the dissociation selectivity can be considerably higher than in the case of a strong single-frequency field. Possibilities of further increase in the dissociation selectivity are considered.
