“…When the projectile velocity becomes slow, the reaction time will increase, and two or more target atoms reacting with the projectile ion would be ionized, which is called Two-Step process [1,2] . In fact, these two mechanisms work in one and the same process, but they take up different proportions between different collision systems and energy ranges [3,4] . In this work, C q+ (q = 1, 2, 3) ions with the energy varying from 0.2 MeV to 6.35 MeV collide with Ar.…”

The ratios of the cross section of the transfer-ionization to the single-electroncapture of Argon induced by C q+ (q = 1, 2, 3) ions are measured by means of position sensitive and time-of-flight techniques. Our experimental results are compared with the data of He q+ (q = 1, 2) − Ar of DuBois. A qualitative interpretation is presented based on the Classical-Over-Barrier Model of Bohr.ion-atom collision, transfer-ionization, single-electron-capture, over barrier model Investigation of highly charged ions collision with atoms is one of the hot points in the field of atom/molecule, especially from the low to an intermediate energy range. We report measurements cross section of the transfer-ionization to the single-electron-capture ratios R, and the projectile energy varies from 0.2 MeV to 6.35 MeV. These investigations are needed in many applications like astrophysics, plasma physics and so on. The process of a projectile A q+ in collisions with an atom B can be expressed as:where the projectile ion A q+ finally captures k electron(s) and changes its charge state to ( ) A , q k − + which is called scattered projectile ion. The target atom B loses r electron(s) and becomes ionized; B r + is the recoil ion. Finally (r − k) electrons are emitted from the collision process. When (r − k) > 0, the reaction is called transfer-ionization (TI) process, and several different mechanisms can contribute to it. In this process, there are two main mechanisms: Shake-Off process and Two-Step process. When the projectile velocity is faster, and reaction time with target atoms is shorter, the probability of capture electron will be smaller. The main reaction channel is direct-single-ionization, and direct-two-ionization of target atoms works because of the Shake-Off process. When the projectile velocity becomes slow, the reaction time will increase, and two or more target atoms reacting with the projectile ion would be ionized, which is called Two-Step process [1,2] . In fact, these two
