Abstract
Triple-differential cross sections (TDCS) have been calculated for the $K$-shell ionization of carbon atom by fast electron impact for highly asymmetric kinematics. In the present calculation the three Coulomb two-body interaction, the dynamic screening modification of these interactions and the correlation in the final channel, the screening effect of the multielectron target, and the distortion of Coulomb force in the initial channel have been taken into account. Results are compared with the relative measurement performed on the ${\mathrm{C}}_{2}{\mathrm{H}}_{2}$ molecule as target. The present TDCS is found to be in better accord with experiment.
