The energy dependent albedo problem of low-energy light ions from heavy targets is considered in a multiple-collision model. The ion transport equation is treated with the assumptions that (i) the distribution function is almost isotropic and (ii) the transport cross section depends only on initial ion energy. The transport equation is Laplace transformed in relative path length and solved by applying the DP0 flux approximation in angle. Reflected energy spectra, particle and energy reflection coefficients are analytically derived. A comparison of DP0 results with age theory, computer simulation data and experimental results is made.

The energy distribution of backscattered ions is obtained in analytical form as a result of approximate solution of the Boltzmann equation. The elastic-scattering cross section is taken in a form corresponding to the screened Coulomb potential which allows investigation of the cases from hard-sphere to Rutherford scattering. Inelastic energy losses are assumed to be proportional to some power of energy. The theory is valid for the case of normal ion incidence on the target surface and for the mass of a target atom much more than the mass of an ion. The first term of expansion of the final result gives the energy distribution obtained in the single-collision approximation and it coincides with the solution known from the previous theories. The theoretical results are verified by their comparison with computer simulation data. ͓S0163-1829͑99͒00533-0͔

An improved bipartition theory for light-ion transport is presented. The improved theory allows the use of accurate but more complex nuclear scattering cross sections and stopping powers in the Boltzmann transport equation, instead of the power function approximation of the nuclear scattering cross sections and the stopping powers used in earlier bipartion theory [Z.-M. Luo and S.-M. Wang, Phys. Rev. B 36, 1885 (1987)]. Furthermore, the theory is extended Tao treat the transport for obliquely incident ions. By the improved bipartition theory, the particle reflection coefficients and energy reflection coefficients, as well as energy distribution of reflected ions for cases of H, D, and He ions incident on C, Ni, Fe, Cu, W, and Au, have been calculated. The comparison of the present calculation results with available experimental data and the Monte Carlo data shows that the improved bipartition model for light ions is useful.The particle reflection coeflcient of ion RN:
