The interference between the normal electric dipole amplitude of the Rb D1 line and the Stark induced magnetic dipole and electric quadrupole amplitude has a linear dependence on the external electric field [rvec [var epsilon]][sub s]. The fractional change in absorptivity due to this interference effect is shown to have the following dependence upon the atomic spin [rvec [sigma]] and upon the polarization [epsilon] and direction k of the light: [Delta][alpha]/[alpha] = (a[sub M1] + a[sub E2])([epsilon][center dot][rvec [var epsilon]][sub s])(k x [epsilon])[center dot][rvec [sigma]]. The coefficient is measured to be: a[sub M1] + a[sub E2] = ([minus]2.53 [+-] .28 [+-] .25) x 10[sup [minus]8](kV/cm)[sup [minus]1]. This result is consistent with a numerical calculation based on a central field model of the Rb atom.
