We report the observation of alignment to orientation conversion in the 7,9 D3/2states of Cs in the presence of an electric field without the influence of magnetic fields or collisions. Initial alignment of angular momentum was created by two-step excitation with linearly polarized light. The appearance of transverse orientation was confirmed by the observation of circularly polarized fluorescence. We present measured signals and compare them with the results of a theoretical model based on the optical Bloch equations. The effect is odd under time reversal and should be taken into account in searches for an electron electric dipole moment.
