在杰斐逊实验室的C厅，测量了质子动量达的类空四动量转移平方的准弹性散射。实验在杰斐逊实验室升级后的C厅进行。它使用现有的高动量谱仪和新的超高动量谱仪来探测符合的散射电子和质子。核透明度被提取为测量的产额与在平面波脉冲近似下计算的产额的比率。此外，还提取了中壳层质子的透明性，并研究了丢失动量分布的不对称性，以寻找量子色动力学预测色透明性的线索。所有这些结果都与传统的核物理学相一致，但与颜色透明的开始不一致。
Quasielastic scattering onwas measured in Hall C at Jefferson Lab for spacelike four-momentum transfer squaredin the range ofwith proton momenta up to. The experiment was carried out in the upgraded Hall C at Jefferson Lab. It used the existing high-momentum spectrometer and the new super-high-momentum spectrometer to detect the scattered electrons and protons in coincidence. The nuclear transparency was extracted as the ratio of the measured yield to the yield calculated in the plane wave impulse approximation. Additionally, the transparency of theandshell protons inwas extracted, and the asymmetry of the missing momentum distribution was examined for hints of the quantum chromodynamics prediction of color transparency. All of these results were found to be consistent with traditional nuclear physics and inconsistent with the onset of color transparency.
