Measurement of thermal energy charge transfer rate of multiply charged molybdenum (molybdenum(6+)) and argon

We have made the first measurement of the thermal energy charge transfer rate of Mo{dollar}\sp{6+}{dollar} and neutral argon. This measurement was carried out using a technique that combines the production of ions by laser ablation and an ion trap. The multiply charged ions produced by laser ablation are cooled by crossed beams collision. These ions are stored in a radio-frequency ion trap. The charge transfer rate is determined by measuring the rate of loss of stored ions in the trap. The charge transfer rate coefficient, k, of Mo{dollar}\sp{6+}{dollar} and Ar is 1.02(.10) {dollar}\times{dollar} 10{dollar}\sp{-10}{dollar}cm{dollar}\sp3{dollar}s{dollar}\sp{-1}{dollar}. The estimated uncertainty is {dollar}\pm{dollar}10% and is mainly due to the uncertainty in the argon density determination and the statistical fluctuation of the ion signals.
