On the ²Σ-Potentials for the Interaction of Potassium(4P) and Potassium(5P) with Argon.
Blue wing satellites were obsd. for K(4P) and K(5P) interacting with Ar at 729.4 +- 0.1 and 403.99 +- 0.01 nm, resp. (classical positions, 65% of the satellite peak). Both the scattering and the line wing profile measurements are simultaneously reproduced quite well by the results from a model potential calcn.; in this calcn. the satellites are found at 727.8 and 404.15 nm for K(4P) and K(5P), resp. These are due to max. in the corresponding difference of the relevant S-potentials located near 7 and 20 a.u. for K(4P) and K(5P), resp.
