Temperature dependence of Cs-Cs<sup>+</sup>charge-exchange cross sections
摘要
A charge-exchange optical-pumping experiment to study the temperature dependence of the Cs-Cs + charge-exchange cross section sigma has been performed. Cs + ions are polarised by resonant charge-exchange collisions with optically pumped Cs atoms. The Cs + ion resonance linewidths are measured over the temperature range 20-26 degrees C. They are used to study the charge-exchange cross section as a function of temperature. The cross section sigma (Cs + to Cs) varies inversely as the square root of the temperature. The charge-exchange cross section sigma (Cs + to Cs) has also been re-measured and found to be (6.6+or-0.5)*10 -14 cm 2 , in good agreement with theoretical calculations.
