ABSTRACT:
A method for the separation of one isotope from other isotopes in a gaseous mixture of isotopes. First the gaseous mixture of isotopes is non-selectively excited by a laser pulse, so as to form spatially localized wavepackets in the isotopes, which initially oscillate in phase with each other. After a certain time interval has passed, during which the wavepackets have undergone substantial revival, the oscillations of the wavepacket in the isotope to be separated are substantially out of phase with respect to the oscillations of the wavepackets in the other isotopes. Following a predetermined time interval the isotope to be separated is selectively excited by another laser pulse and thereafter extracted from the gaseous mixture.
