Isotopic selectivity of pulsed excitation of zinc atoms upon the 4s2 1 S0 → 4p 3P01 transition

The spectral dependences of the isotopic selectivity of the optical excitation of zinc atoms in the course of an efficient photochemical reaction with molecules of a reagent gas are calculated within the framework of a simple model taking into account the gas mixture flow. At a certain frequency detuning of monochromatic laser radiation, a high selectivity of isotope separation is realized at the end of the interaction region under the condition that the isotopic shifts are smaller than the Doppler broadening.
