We have measured the ejected electron signals from Ba 6p{sub 1/2}nk autoionizing Stark states, of n=28 and 29, produced by linearly polarized laser excitation in weak electric fields. These states do not have well-defined parities and as a result do not lead to angular distributions which are up-down symmetric with respect to the laser polarization direction. The weakness of the electric field makes the observation of the up-down asymmetry of the ejected electrons possible. We observe that the electrons from Ba 6p{sub 1/2}nk autoionizing red states are ejected in the upfield direction, while the electron from Ba 6p{sub 1/2}nk autoionizing blue states are ejected in the downfield direction.
