【 摘 要 】

An overview is provided of the convergent close-coupling calculations for electron- impact on neutral beryllium, as well as its various ionic stages. The calculations were performed from near threshold to high energies with initial states having principal quantum number n ≤ 4. Excitation to states with n ≤ 5 and total ionisation cross sections have been calculated with an estimated accuracy of below 10% at all energies considered.
