| Abstract: | The double-to-single ionization ratios of He induced by partially striped F q (q=1,2,3,4) projectiles with energies ranging form 1.5-7.5 MeV were measured using TOF(time-of-flight) technique. the influence on the collision by electrons bound to the projectiles were discussed. The n-body classical trajectory Monto Carlo calculation was applied to the same collision system. The results of CTMC calculation were analyzed and discussed. |
