It is proposed and studied a new optimal theoretical scheme for the laser photoionization sensor of the separating isotopes, nuclear isomers and nuclear reactions products, which is based on the selective laser excitation of the isotope atoms into excited Rydberg states and further stochastic collisional ionization mechanism. The operator perturbation theory and FockerPlank stochastic equation method are used for description of stochastic collisional ionization process. The optimal laser action model and density matrices formalism is used for numeric calculation of the optimal scheme of the Na, U, Cs and Cf isotopes (ions, nuclei) sensing.It is proposed and studied a new optimal theoretical scheme for the laser photoionization sensor of the separating isotopes, nuclear isomers and nuclear reactions products, which is based on the selective laser excitation of the isotope atoms into excited Rydberg states and further stochastic collisional ionization mechanism.

The formation of ${\mathrm{Na}}^{+}$ and ${\mathrm{Na}}_{2}^{+}$ in sodium vapor (\ensuremath{\sim} ${10}^{11}$ - ${10}^{13}$ ${\mathrm{cm}}^{\ensuremath{-}3}$) containing laser-selected Rydberg atoms $(15<~n<~35)$ has been studied. At low atom densities photoionization, collisional ionization, and associative ionization dominate, but more-complicated mechanisms contribute to the ion yield at higher densities.The formation of ${\mathrm{Na}}^{+}$ and ${\mathrm{Na}}_{2}^{+}$ in sodium vapor (\ensuremath{\sim}${10}^{11}$-${10}^{13}$ ${\mathrm{cm}}^{\ensuremath{-}3}$) containing laser-selected Rydberg atoms $(15<~n<~35)$ has been studied.
