• The angular distributions are obtained of multiply scattered particles for various impact energies (0.4∼1.5 MeV for protons and 1.3∼4.5 MeV for nitrogen ions), foils (aluminium, copper, silver and gold) and their thicknesses. The data agree fairly well with theories of Moliere and of Keil, Zeitler and Zin with the use of Thomas-Fermi radius which takes account of both projectile and target atom. The slight deviations found when the mean number of scatterings in the foil is smaller than about 20 are attributed to an underestimation of Moliere's single-scattering cross section in the small angle region. The theory of Nigam, Sundaresan and Wu shows a large discrepancy from the observations, and that of Meyer also gives a little deviation when the mean number of scatterings is smaller than about 10.
