A method and an apparatus for the separation of isotopes from an atomic or molecular paramagnetic or polar beam of isotopic mixtures, by the utilization of the isotopic differences of said atoms as well as molecules, in the Electron Spin Resonance (E.S.R.) spectra and in other magnetic or electric resonances such as in the Nuclear Magnetic Resonance (N.M.R.) or Stark Resonance, is disclosed. The apparatus comprises means for producing a paramagnetic or polar particle beam of an isotopic mixture; means for changing the distribution of the mj values in said particle beam to at least one beam having a discrete mj value or values, where mj is the projection of the angular momentum of a particle in the direction of the applied magnetic field or the projection of the rotational angular momentum of the polar molecular in the direction of the applied electric field; means for producing a homogeneous magnetic or electric field along a section of the path of said particle beam; a transmitter for transmitting signals in at least one of the E.S.R., and/or N.M.R. and/or a Stark resonance frequency or frequencies of at least one of the isotopes in said particle beam passing through said homogeneous magnetic or electric field; and means for producing an inhomogeneous magnetic or electric field gradient for separating said isotopes by splitting, focusing and/or diverting beams of identical isotopes.
