Abstract
The interest on isotopes and their applications increased in many fields such as nuclear power generation
and medicine. Laser isotope separation is a promising technique for its high selectivity and efficiency.
Isotopes of Gd and Zr, which are important materials in nuclear engineering, can be separated by
selective stepwise or multiphoton ionization method based on polarization selection rules. Development
of isotope separation of 93Zr, 126Sn, and 135Cs is desired for future nuclear transmutation of long-lived
fission products. Separation method of 48Ca by radiation pressure is proposed for double-beta- decay
experiment.
