【 摘 要 】

A relativistic approach, based on the relativistic many-body perturbation theory (PT) with using the optimized Dirack-Kohn-Sham wave functions sets, is applied to computing the hyperfine structure collision shift for the thallium atom in atmosphere of the inert gases (A=He,Ar, Xe). Data for the collisional shifts of the Tl-A system are presented and compared with other available ones.
