Abstract: | This paper uses the two-centre atomic orbital close-coupling methodto study the ionization and the single electron capture in collisionof highly charged Ar16+ ions with He atoms in the velocityrange of 1.2--1.9 a.u.. The relative importance of single ionization(SI) to single capture (SC) is explored. The comparison between thecalculation and experimental data shows that the SI/SC cross sectionratios from this work are in good agreement with experimental data.The total single electron ionization cross sections and the totalsingle electron capture cross sections are also given for thiscollision. The investigation of the partial electron capture crosssection shows a general tendency of capture to larger n and lwith increasing velocity from 1.2 to 1.9 a.u.. |
