Multiple electron transfer processes in collisions of low energy Ar9+ ions with Na atoms

Using the new built research facility for atomic physics in Institute of Modern Physics, multiple electron transfer processes were studied in the collisions of Ar9+ ions with Na atoms at 180 keV. A combination of position sensitive and time-of-flight techniques was used. 8 reaction channels are identified from the experimental data and the results were compared with the predictions of the molecular Coulombic over barrier model by considering the autoionization decay and electron evaporation of multiply excited sates in projectiles and recoil ions respectively.
