Abstract: | Experimental data for separation of neodymium isotopes by atomic vapor selective laser photoionization are analyzed. Atom
scattering in the working volume and the Doppler shift of the atom absorption line are shown to be the basic deselecting processes
in the experimental cell studied. A data processing technique that allows one to determine the effect of either deselecting
process on the product enrichment and yield is suggested. The experimental dependence of the target isotope concentration
in photoions present in the separating chamber on the angular divergence (collimation) of the atomic vapor flow along the
laser beam is found. A method for determining the vapor flow optimal angular collimation is developed. |
