LASER PHOTOIONIZATION SENSOR OF THE SEPARATING HEAVY ISOTOPES AND NUCLEAR ISOMERS: SELECTIVE IONIZATION BY DC ELECTRIC AND LASER FIELD (U, Tm)

Abstract

It is proposed and studied a new optimal theoretical scheme for the laser photoionization sensor of the separating heavy isotopes and nuclear isomers, which is based on the selective laser excitation of the isotopes atoms into excited Rydberg states and further DC electric field ionization. The operator relativistic perturbation theory method, optimal laser action model and density matrices formalism are used for numeric calculation of the optimal scheme parameters for the Tm, U isotopes (ions, nuclei) sensing
