摘要：

Total and partial cross sections are calculated for single-electron capture in B3+-He collisions for projectile energies from 1.0 to 500 keV. Results for a one-electron model and a full two-electron treatment of the electronic wave function are compared. Both procedures compare well with experimental data for total cross sections. However, the two-electron model, which incorporates correlation and relaxation effects, compares most favorably, particularly when partial cross sections are considered. The total single-capture cross sections for higher velocities (upsilon almost-equal-to 2-8 a.u.) decay in average according to a upsilon-7.2 behavior, close to the upsilon-7 behavior expected from the Bohr-Lindhard model. The discussion focuses on the role of correlation effects during the collision.
