The quantum-mechanical broadening of classical Thomas peaks in various fast second-order particle transfer processes is considered in observable velocity distributions of recoil particles. The relativistic, two-center, coupled-channel treatment of atomic collisions between high-Z ions has been extended to include pseudostates and reasonable estimates of the cross sections for ionization and K-vacancy production are obtained. Correlation effects in the excitation processes of two-electron atoms are investigated by means of the hyperspherical coordinate method. Charge transfer processes of multi-electron systems are studied by a close-coupling method based on a molecular orbitals attached by electron-translation factors. The continuum multiple-scattering method is applied to the scattering of relatively large molecules. A network connection between Japanese and US computers has been established for the calculations of charge transfer processes.
