摘要：
Relative differential electron impact cross sections (sigma(theta)) for elastic and inelastic (3p, 4s, 3d, 4p) scattering at 10 eV, 20 eV (3p and 4s excitation only) and 54.4 eV by sodium atom have been measured. The sigma(theta) for the 3s-3p transition are normalized to the optical oscillator strength. The angular range of measurements is from 2-degrees for inelastic and from 6-degrees for elastic scattering, up to 150-degrees for both. Results are compared with the available experimental and theoretical data. Present results of sigma(theta) are lower at large scattering angles than coupled-channel theory predicts. Comparison with the recent distorted wave calculations by Madison et ai is given in the following paper.
