【 摘 要 】

Single ionization of helium produced by 100 MeV/u C6+projectiles is studied theoretically. The ionization amplitudes are calculated by directly solving the two-electron Schrödinger equation in the framework of the semiclassical impact parameter approach. Projectile coherence effects are investigated through fully differential electron emission cross section ratios resulting from coherent and incoherent calculations based on the same amplitudes. The obtained results are compared to existing theories and experimental data, as well.
