Azimuthal asymmetry of the differential cross sections between two polarized states has been measured in elastic electron scattering by laser-excited sodium atoms prepared in the 3{sup 2}{ital P}{sub 3/2},{ital F}=3 ({ital M}{sub {ital F}}=+3 or {ital M}{sub {ital F}}={minus}3) polarized state. These results are an observation of the orbital effect in the elastic electron collision due to {ital M}{sub {ital L}} atomic state perpendicular to the scattering plane. Data are reported for electron energies in the range of 1{endash}10 eV, comparable with the kinetic energy of the atomic valence electron. At polar scattering angle {theta}=135{degree} we found the asymmetry to be more significant when the incident electron energy is lower. Differential cross sections of these excited, polarized states were obtained at 135{degree} as a function of electron energy as well. The experimental results are compared with {ital R}-matrix-based close coupling, and convergent-close-coupling calculations. {copyright} {ital 1996 The American Physical Society.}
