摘要：
We calculate the asymmetry parameter, A, for the electron scattering reaction, e+He-3 --> e+He-3, run with right and left handed polarized electrons. We have calculated this reaction at energies from .1 GeV to 6 GeV. We present here the results for this reaction run at 1 GeV as an example. We obtain both A and a figure of merit. We find a sharp and unexpected variation in A due to cancellation between the weak and electromagnetic form factors. This is caused by the different q(2) dependences of the weak and electromagnetic form factors. Unfortunately in this region the figure of merit is small.
