Abstract
The cascade decay of the 6S(4D) levels of the potassium atom, 6S(4D)-5 P-5S(3D)-4P, following two-photon excitation of potassium vapor (4S-4P -6S) is investigated experimentally. The dependences of 11 resonant IR line intensities on potassium and buffer gas densities are presented. It is shown that the presence of buffer gas leads to collisional redi stribution of radiation, causing suppression of some lines and product ion of new ones.
