On the possibility of determination of the orientation relaxation time of the thallium level by means of modified stimulated photon echo

Abstract

The electric field strength of the modified stimulated photon echo signal formed on the hyperfine structure components of the thallium levels 6 2 P 1 2 (F=1), 6 2 P 3 2 (F=1) and 7 2 S 1 2 (F=0) is calculate. The possibility of determination of the orientation relaxation time of the metastable 2 P 3 2 thallium level with the use obatined theoretical relations is pointed out.
