Abstract
The experimental method is discribed for measuring angular distributions of sputtered particles using a sputtered particle collector and Rutherford backscattering analysis. The angular distributions are given for 100keV Ar

ions sputtering of Ag at incident angles of 0°
30°
50° and 80°. The angular distributions have large deviations from the cosine distribution and show an anisotropy with a preferred emission in forward direction with respect to the beam. The differential sputtering yield increases rapidly with increasing angle of incidence. The total sputtering yield calculated from the angular distribution for 50 keV Ar

sputtering of Ag is 16.8±2.4 atoms/ion and compared with theoretical values. Finally
the results are discussed qualitatively.
