The single-center convergent close-coupling (CCC) method is applied to calculate positron scattering from beryllium. A model potential approach is utilized to extract positronium formation, direct ionization, and values between the positronium formation and direct ionization threshold. For this scattering system, we present results for total, electron loss, elastic, momentum transfer, excitation, positronium formation, direct ionization, stopping power, and mean excitation energy from threshold to 5000 eV. A modified independent atom approach is used to calculate total, electron loss, and elastic cross sections for beryllium oxide for energies above 1 eV. For beryllium, good agreement is viewed with past theory for intermediate and high energies. At lower energies, different theoretical models exhibit substantial differences.
