Abstract

Abstract: The use of atomic vapour laser isotope separation (AVLIS) for solving a number of urgent problems (formation of 177 Lu radionuclides for medical applications, 63 Ni radionuclides for betavoltaic power supplies and 150 Nd isotope for searching for neutrinoless double β decay and neutrino mass) is considered. An efficient threestep scheme of photoionisation of neodymium atoms through the 50474-cm -1 autoionising state with radiation wavelengths of the corresponding stages of λ1 = 6289.7 Å, λ2 = 5609.4 Å and λ3 = 5972.1 Å is developed. The average saturation intensity of the autoionising transition is ∼6 W cm -2, a value consistent with the characteristics of the previously developed photoionisation schemes for lutetium and nickel. A compact laser system for the technological AVLIS complex, designed to produce radionuclides and isotopes under laboratory conditions, is developed based on the experimental results.
