准弹性散射是在类空4-动量转移平方，9.4，11.4，和，迄今为止达到的最高水平。该反应的核透明度是通过将测量的产额与没有任何终态相互作用的平面波脉冲近似计算的预期产额进行比较来提取的。测量的透明度是一致的，没有依赖性，质子动量，排除了量子色动力学效应的颜色透明度在测量尺度上的排他性反应。这些结果对质子的颜色透明度模型施加了严格的限制。
Quasielasticscattering was measured at spacelike 4-momentum transfer squared, 9.4, 11.4, and, the highest ever achieved to date. Nuclear transparency for this reaction was extracted by comparing the measured yield to that expected from a plane-wave impulse approximation calculation without any final state interactions. The measured transparency was consistent with nodependence, up to proton momenta of, ruling out the quantum chromodynamics effect of color transparency at the measuredscales in exclusivereactions. These results impose strict constraints on models of color transparency for protons.
