Measurements of the scattering of high energy electrons are proposed to provide a better understanding of the structure of nucleons and of few-body nuclear systems. At the SLAC accelerator, 50 GeV electrons are being used to understand the spin structure of the nucleon. At the new TJNAF laboratory high energy electrons will be used to measure the magnetic form factor of the neutron and to measure the electric elastic structure function of the deuteron to high momentum transfer to provide tests of various theories. Additional measurements of the structure of helium nuclei are also proposed.

高能电子散射的测量是为了更好地理解核子和少体核系统的结构。在SLAC加速器上，50 GeV电子被用来理解核子的自旋结构。在新的TJNAF实验室，高能电子将被用来测量中子的磁形状因子，并测量氘核到高动量转移的电弹性结构函数，以提供各种理论的测试。还提出了氦核结构的其他测量方法。
