Recent progress in improving our knowledge of the four nucleon form factors G{sup p}{sub M}, G{sup p}{sub E}, G{sup n}{sub M}, G{sup n}{sub E} at high momentum transfer is stimulating a new wave of theoretical efforts to describe these fundamental quantities. Both model calculations and lattice QCD can predict the elastic form factors; a definitive, stringent test of these efforts is to predict all of them simultaneously. However, the limited range and quality of the data for the neutron magnetic form factor G{sup n}{sub M} presently reduce the discriminating power of such a test. The present status of our knowledge of G{sup n}{sub M} is discussed, and prospects for future improvements are presented. |
