Experimental measurements of electron impact excitation of the 6p7s {sup 3}P{sub 0,1} states of Pb atoms have been made at incident electron energies E{sub 0}=10, 20, 40, 60, 80, and 100 eV and scattering angles from 10 deg. to 150 deg. In addition, relativistic distorted-wave calculations have been carried out at these energies. The data obtained include the differential (DCS), integral (Q{sub I}), momentum transfer (Q{sub M}), and viscosity (Q{sub V}) cross sections. Absolute values for the differential cross sections have been obtained by normalizing the relative DCSs at 10 deg. to the experimental DCS values of [S. Milisavljevic, M. S. Rabasovic, D. Sevic, V. Pejcev, D. M. Filipovic, L. Sharma, R. Srivastava, A. D. Stauffer, and B. P. Marinkovic, Phys. Rev. A 75, 052713 (2007)]. The integrated cross sections were determined by numerical integration of the absolute DCSs. The experimental results have been compared with the corresponding calculations and good agreement is obtained.
