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