1. Introduction
The investigation of electronic reactions in collisions between ions and molecules
is relevant to many fields, including plasma physics, astrophysics, medical physics,
and radiobiology. In particular, in plasma-facing applications, beryllium and boron
have emerged as promising candidate materials for plasma—wall interfaces. In the
literature, numerous theoretical studies have computed total cross-sections (TCSs)
for collisions between highly charged bare ions and neutral atoms. The interaction between dressed projectiles and neutral atoms has been investigated by Das et
al. [1] using perturbative methods such as the boundary-corrected continuum intermediate state (BCCIS) approximation, as well as by non-perturbative approaches
(see Ref. [2] for a review).
2. Methods
The present work aims to investigate single-electron capture processes from multi-
electron atoms induced by collisions with multi-charged, dressed projectiles at
intermediate and high energies. This process is studied within the Continuum
Distorted Wave (CDW) formalism, extending the recent development of Quinto
et al. [3]—originally formulated for hydrogen—to multi-electron targets. In this
work, the interaction between the projectile and the active electron is described
by the analytic Green–Sellin–Zachor (GSZ) potential. The electrons bound to
the projectile are treated as frozen during the collision. The final states of the
projectile are described by excited atomic wave functions [4].
3. Results
The results in terms of total cross-sections are compared with both experimental
measurements and available theoretical data over the energy range from 10 keV/u
to 10 MeV/u.
