Charge Exchange Cross Sections of Carbon Ions

Based on experimental data on the ion charge distributions, the cross sections of single electron loss sigma(i, i + 1) and single electron capture sigma(i, i - 1) by carbon ions with velocities (2.7-8) x 10(8) cm/s in different gaseous media (He, N(2), and Ar) have been obtained. Regularities of the cross section variation of the electron capture and loss by carbon ions as a function of the ion velocity, ion charge, and atomic number of the target have been for the first time studied in a wide range of the initial ion charge, from i = 0 to i = 6. A qualitative agreement of the obtained results with the published data has been established for a number of other ions. Theoretical calculations of the cross sections of single electron loss by carbon ions in helium have been carried out.
