The multiple scattering of 40 pi mesons which came to rsat in a G5 nuclear emulsion was measured by means of the tangent methed. The direction of a double cell can be determined from the mean direction of two consecutive single cells forming the double cell. The noise between double and single cells was thus eliminated. Formulas proposed for the elimination are verified by this study. The multiple scattering constant deduced from the study of pi mesons of energy 6 to 12 Mev is, within experimental error, in good agreement with the theoretical value. The distribution of scattering angles is gaussian for angles 4 times smaller than the mean angle, but for greater angles, tbere is a signifcant excess. The ratio between the second difference and the angle of multiple scattering is of the same order as that found by the sagitta method. (auth)
