"Starting in 1994, yet another scheme has been proposed for deuterium separation using Trojan wave packets formed in a circularly[6] or linearly[7] polarized electromagnetic field. The process of Trojan wave packet formation by the adiabatic-rapid passage depends in an ultra-sensitive way on the reduced electron and nucleus mass so that the same field frequency leads to excitation of Trojan or anti-Trojan wave packets depending on the isotope.[8] In theory, Trojan wave packets and their giant, rotating electric dipole moments could then be -shifted in phase and the atomic beam split in the gradient of the electric field in an analogous way to the Stern–Gerlach experiment.[citation needed]
