Abstract/Summary:
A new method is developed that combines the production of ions by laser ablation with a reflection time-of-flight mass spectrometer (RTOFMS) for charge-transfer cross section measurements. This method allows a specific charge-transfer channel of an ion-neutral pair to be measured at energies of about 0.1 KeV/amu. The charge-transfer cross section is determined by measuring the intensity ratio of the product ions to the parent ions after the charge-transfer reactions occur in the reflection drift tube of the RTOFMS. First, a calibration measurement of C...
