Abstract : The experiment reported here is an attempt to detect effects of a dawn-to-dusk electric field of the type implied by recent models of plasma convection in the magnetosphere. Outer radiation zone electron intensities measured near dawn and dusk are compared as for three magnetically quiet periods. A requirement of the experiment is to examine the outer-zone steady state and in particular to avoid local time dependent effects of nonadiabatic acceleration processes. For this reason the quiet periods were selected by choosing intervals of a few days each when the outer-zone intensity showed a steady decay. (Author)
