ule{-0.16em}{0ex}}{D}_{2}$ state in Yb have been considered. Differential and integrated cross section results have been obtained and compared with recent experimental results and theoretical convergent close coupling calculations. In general, good agreement between the theoretical calculations and experimental measurements has been observed.
