Absolute cross sections for charge-exchange in 3He2+ and H+ impact on CO

Year: 2002

Type: article

Abstract: We report measured absolute single and double charge-exchange cross sections for 3 He 2+ on CO at ion impact energies between 1 and 14 keV (velocities between 254 and 949 km s -1 ). A retarding-field method is used for charge-state analysis of the ion beam after traversing the target gas cell. Cross sections are determined from absolute measurements of current ratios and the CO target gas pressure. For testing the experimental technique, proton-electron capture cross sections are measured at energies between 2.5 and 7 keV. The measured He 2+ and H + cross sections are compared to available data.
