Abstract
We present an advanced, optimal laser-photoionization scheme of separating heavy radioactive isotopes and nuclear isomers, in particular, the uranium isotopes and the transuranium elements. The advanced scheme is based on the selective laser excitation of the isotope atom into the highly-excited Rydberg states and further electric field ionization mechanism. Some preliminary data for the autoionization resonance characteristics for U and transuranium isotopes are obtained. An appreciable dependence of the reorientation decay velocity of the autoionization resonances at an electric field is analyzed. Two autoionization resonances decay channels are predicted as well as the effect of the giant autoionization resonance width broadening in the relatively weak electric field for uranium and transuranium elements. Using the optimal laser action model and density matrices formalism it has been carried out modelling the optimal scheme of the U isotopes separation. It is presented The optimal scheme g- laser on quickly decayed nuclear isomers with using laser photoionization sorting excited nuclei with autoionization and electric field ionization mechanisms.
