The elastic scattering of high-energy electrons at 180 from He has been discussed with the purpose of determining an upper limit to the electric dipole moment Î» of the electron. Our calculations have shown that, with the Saskatchewan Linear Electron Accelerator, it will be possible to measure an upper limit as small as Î» â‰¤ 7.1 x 10-6 [(eth)/(mâ€¢c)] without cancellation or masking of the effect of Î» on the final results by the second-order effects. Our calculations include the effects, on the final results, of energy losses and multiple scattering encountered by the electrons in traversing the target.
