We present angle-differential and angle-integrated cross sections for electron-impact excitation of the (4d105s)S1/22→(4d95s2)D3/22 and (4d105s)S1/22→(4d106s)S1/22 transitions in atomic silver. Experimental data for four incident electron energies between 10 and 60 eV are compared with predictions from our relativistic distorted wave (RDW) and nonrelativistic atomic optical potential models. Agreement between our measured and calculated data is only fair, although in the case of the RDW it is seen to improve with increasing incident electron energy. However, only for the (4d106s)S1/22 excitation process, agreement of our measured data with earlier relativistic convergent close coupling results from McNamara [J. Phys. B 51, 085203 (2018)]JPAPEH0953-407510.1088/1361-6455/aab420 was, with a few exceptions, typically observed to be very good, to within the uncertainties on the data.
