✦ Synopsis

We have studied the orienting effect that an electric field has on the orbital motion of the pairs in superfluid 3He-B, using the orientation-dependent transverse NMR frequency shift as a probe. This method provides high resolution for studying the orienting effect for either sign of the orientational energy. Electric fields as high as 35,000 V/cm applied across the sample produced no measurable frequency shift at 0-, 10-, and 32-bar pressures. This gives upper limits to the orientational energy of 1.4x lO -3, 1.0 x 10 -3 and 4 x 10 -4 times the values expected from simple theory.
