The (2)H(e,e'p)n cross section at a momentum transfer of 3.5 (GeV/c)(2) was measured over a kinematical range that made it possible to study this reaction for a set of fixed missing momenta as a function of the neutron recoil angle θ(nq) and to extract missing momentum distributions for fixed values of θ(nq) up to 0.55 GeV/c. In the region of 35°≤θ(nq)≤45° recent calculations, which predict that final-state interactions are small, agree reasonably well with the experimental data. Therefore, these experimental reduced cross sections provide direct access to the high momentum component of the deuteron momentum distribution in exclusive deuteron electrodisintegration.
在动量转移为 3.5（GeV/c）的情况下，测量了（2）H(e,e'p)n 截面，其运动学范围使得有可能研究一组固定缺失动量作为中子反冲角θ(nq)的函数的反应，并提取固定值θ(nq)的缺失动量分布，最高可达 0.55 GeV/c。在 35°≤θ(nq)≤45°的区域，最近的计算预测，末态相互作用很小，与实验数据相当吻合。因此，这些实验的缩减截面为研究在排除的氘核电分解中氘核动量分布的高动量成分提供了直接途径。
