Two- and three-steps selective photoionization of lithium atoms and dimers

  • 1. RNTs Kurchatovskij Inst., Inst. Molekulyarnoj Fiziki, Moscow (Russian Federation)

Description

Two- and three-steps selective photoionization of Li6 atoms was performed using continuously operating dye lasers. During ionization through the 3P3/2 and 3D5/2 levels the selectivity S = 2400 was achieved. The selectivity S = 24000 was achieved during ionization through the 2P1/2 and 3D3/2 levels. Selective photoionization of the lithium dimers was conducted using Ar+ laser. For the different discrete wavelengths of the laser the enrichment as 6Li2, so 7Li2 was obtained. Maximum separation coefficient of 6Li2 was S = 14 for the 465,8 nm line

Abstract (Russian)

Произведена двух- и трехступенчатая селективная фотоионизация атомов Li6 с помощью лазеров на красителях непрерывного действия. При ионизации через уровни 3P3/2 и 3D5/2 достигнута селективность S = 2400. При ионизации через уровни 2P1/2 и 3D3/2 достигнута селективность S = 24000. С помощью Ar+ лазера проведена селективная фотоионизация димеров лития. Для различных дискретных длин волн лазера получено обогащение как 6Li2, так и 7Li2. Максимальный коэффициент разделения для 6Li2 составил S = 14 для линии 465,8 нм
