Abstract
Results of the SND experiment at the VEPP-2M e(+)e(-) collider on the QED p rocesses e(+)e(-) --> e(+)e(-)gamma and e(+)e(-) --> e(+)e(-)gamma gamma wi th production at large angles are presented. The energy and angular distrib utions of the final particles were studied. No deviations from QED were fou nd, with an accuracy of 3.8% for the first process and 10.3% for the second .
