We develop a classical electrodynamical theory of the dielectric function for an inhomogeneous electron gas. The dielectric function in the high-frequency approximation (HFA) derived by Kitagawa is obtained in a simple manner. It is shown that, in an

We calculate the emergence angle dependent energy loss of high energy ions, using the transport theory developed by Jakas et al. and by Yamashita. We developed the theory of impact parameter dependent stopping power taking into account the Barkas eff

We calculate the self-energies of positrons and electrons in solids. Our calculation shows that the imaginary part of the self-energy of positrons is much enhanced in comparison with that of electrons, which explains the recent experiments. The diffe

Positronium formation spectroscopy is discussed theoretically and a comparison is given with experiments on the glancing-angle surface scattering of positrons. The theoretical calculation of the positronium angular distribution agrees with the experi

Numerical calculations of charge exchange scattering are done on the basis of the semiclassical Anderson-Newns hamiltonian. The validity of the various approximation theories is examined in the limit of the semiclassical theory. Moreover the quantum

A quantum-mechanical theory of positronium formation at surfaces is presented. The neutralization probability of positrons implanted into solids escaping from a surface is calculated. The theory of the resonant neutralization of ions at a surface is
