The possibility of laser isotope separation of Yb from irradiated natural Yb has been investigated. The optimum process parameters such as powers and bandwidths of the lasers, Doppler broadening and the number density of the atoms have been derived through density matrix calculations. It has been shown that it is possible to produce Yb (>42% enriched) at a production rate of 62 μg/hour (or 1.

The feasibility of laser isotope separation of Pd through pulsed laser optical pumping followed by isotope selective photoionization has been studied through density matrix formalism. The effect of various parameters such as bandwidth of the excitation lasers, intensity of the lasers and Doppler broadening of the atomic ensemble on the efficiency of optical pumping and isotope selective photoionization have been evaluated. The optimum number density in the laser-atom interaction region has been derived from the studies of the effect of charge exchange collisions on the degree of enrichment.

A three-step photoionization has been theoretically studied for the laser isotope separation of Ra through the following photoionization scheme. [Formula: see text] The effect of bandwidth, peak power density of the excitation and ionization lasers, Doppler broadening of the atomic ensemble, number density of the atoms, and charge exchange collisions on the laser isotope separation process has been studied. The optimum system parameters for the separation of Ra through this photoionization scheme have been derived.

A 562 nm-627 nm-597 nm three-step resonant photoionization scheme has been studied using the density matrix formalism for the enrichment of Nd in weighable quantities for the neutrinoless double-beta decay detection. The effect of bandwidth of the excitation laser and charge exchange collisions, on the production rates and degree of enrichment has also been studied. Optimum conditions for the efficient enrichment of Nd isotope have been derived.
