摘要：

Approximations to treat the screening and scattering of a slow dicluster by independent electrons of a homogeneous system are used to investigate the vicinage effect in the stopping power for the composite. A partial wave expansion is employed for the scattering amplitudes to treat the coherent elastic scattering of the electrons by the two independent scattering centers. For proton dicluster stopping, a simple analytical expression is obtained in the one-phase-shift approximation. Good agreement with the available experimental data is found. © 1990.
