Abstract

Cross-section ratios have been determined for the collisional transfer of electronic energy from the resonance levels of K to those of Rb. The results obtained were $\frac{Q (K {}^{2}P_{\frac{3}{2}} \to Rb {}^{2}P_{\frac{1}{2}})}{Q (K {}^{2}P_{\frac{1}{2}} \to Rb {}^{2}P_{\frac{1}{2}})} = 1.1 \pm 0.2$ $\frac{Q (K {}^{2}P_{\frac{3}{2}} \to Rb {}^{2}P_{\frac{3}{2}})}{Q (K {}^{2}P_{\frac{3}{2}} \to Rb {}^{2}P_{\frac{1}{2}})} = 2.2 \pm 0.2$ $\frac{Q (K {}^{2}P_{\frac{3}{2}} \to Rb {}^{2}P_{\frac{3}{2}})}{Q (K {}^{2}P_{\frac{1}{2}} \to Rb {}^{2}P_{\frac{3}{2}})} = 1.0 \pm 0.2$ $\frac{Q (K {}^{2}P_{\frac{1}{2}} \to Rb {}^{2}P_{\frac{3}{2}})}{Q (K {}^{2}P_{\frac{1}{2}} \to Rb {}^{2}P_{\frac{1}{2}})} = 2.2 \pm 0.6$ where the errors quoted are purely statistical. Possibilities of systematic errors are discussed. Combined with the absolute cross sections of Ornstein and Zare, these ratios give a complete set of cross-section values, namely, $Q (K {}^{2}P_{\frac{1}{2}} \to Rb {}^{2}P_{\frac{1}{2}}) = 2.3 \pm 0.6$ $Q (K {}^{2}P_{\frac{1}{2}} \to Rb {}^{2}P_{\frac{3}{2}}) = 5.3 \pm 0.8$ $Q (K {}^{2}P_{\frac{3}{2}} \to Rb {}^{2}P_{\frac{1}{2}}) = 2.5 \pm 0.5$ and $Q (K {}^{2}P_{\frac{3}{2}} \to Rb {}^{2}P_{\frac{3}{2}}) = 5.5 \pm 1.2$
