摘要：

Energy-loss spectra of swift light ions have been calculated by the transfer-matrix method. An accurate numerical evaluation of a realistic model for 32 MeV He-3 penetrating carbon foils served as a reference standard. The conventional diffusion approximation has been generalized to multi-state systems. As a main result we found a representation with an accuracy going significantly beyond that of a sum of Gaussians. Our results are in good accord with recent experiments on charge-state-dependent stopping.
