摘要：

The coupled-channel method is used to calculate excitation, single- and double-ionization cross-sections for helium collisions with heavy ions. The wave functions of the channels are helium wave functions constructed with Slater functions and Coulomb wave packets. Results of calculations with various projectiles and incident energies are compared with experimental data and other theoretical cross-sections.
