Abstract
An analysis of the generation mechanisms of the electron-excited potassium molecules K2(A'Σ +u) made in paper [1] has revealed a high efficiency of the reaction K(4P) + K(4S) [MATH] k2(A'Σ +u) + h√ (1) According to [2] the collisional excitation transfer from atom to molecule may be considerable under some conditions K(4P) + K2(X'Σ +g) [MATH]K2(A'Σ +u) + K(4S) (2) In present work the role of abovementioned processes in a discharge potassium plasma at medium pressures p = (0.1 + 1.0) torr was investigated and the cross-sections q1 and q2 for reactions (1) and (2) were estimated by rather simple method.
