“…From the IA I-mixing cross sections c s k x in the intermediate-n region (n= [10][11][12][13][14][15] of the Na atom (see table 3), a kind of fit formula can be obtained, which has been discussed in our previous work (Liu et al 1991b), in which the parameters A and p can be determined by using the least-squares fit method, where /3=-2.752, -3.641 and -1,002, respectively, for the collision systems Na-He, Na-Ne, and Na-Ar. Instead of using formula (2.…”

We propose a theoretical description of the /-mixing process of alkali-metal atoms in thermal collision with neutral perturber atoms within the framework of an eikonal approximation. Our present work overcomes to some degree the weakness of those current theoretical methods neglecting the interaction between the penurber atom and the alkalimetal atomic core and treating the collision system as a tao-body one. The present theoretical cross Seaions for the /-mixing processes of Na and Rb atoms exhibit a similar dependence on the principal quantum number n io that of the experimental results of Gallagher, Edelstein and Hill and Hugon er d.

We have presented a theoretical description of J-mixing (the transfer of excitation between fine structure) cross sections of a Rydberg Cs atom induced by thermal collisions with noble-gas atoms. The theory is based on the application of impulse approximation theory and a kind of model-potential wave function. The results agree well with available recent experimental values for He, Ne, and Ar atoms.But for the heavier noble-gas atoms Kr and Xe, the theoretical cross sections are larger than the experimental ones.PACS number(s):
