N2 - The excitation spectra of atoms and solids by radiation impact have been studied using the local-plasma approximation. In the former system, atomic generalized oscillator strengths were computed with the electron density distribution for atoms obtained from the Hartree-Fock-Slater model. In the latter system, the energy-loss functions were calculated based on the Drude dielectric function of electron gases and the Hartree-Fock-Wigner-Seitz electron density distribution for the first-order solid atoms. In all cases, sum rules of various orders have been tested. Comparison of present results with other theoretical values and experimental data has been made.
