Abstract: | Weighted average cross sections for quenching of the K(42P)-doublet by N2, H2, O2 and H2O, measured in flames, show no significant temperature dependence in the range from 1500 to 2500K. Doublet mixing cross sections for K(42P?42P) transitions were measured at 1720K for N2, O2, H2O. The ratios of both mixing cross sections were measured independently and were found to agree with the detailed balance condition within 2 per cent. It is shown that an ionic intermediate-state model cannot explain the large magnitude of N2? mixing cross sections. |
