标题： Inclusive Electron-Nucleus Scattering at Large Momentum Transfer

摘要： 包含电子散射在4.045 GeV入射束能量下对C、Fe和Au靶进行了测量。 测量的能量转移和角度对应于Bjorken$x > 1$的运动学范围以及动量转移从$Q^2 = 1 - 7 (GeV/c)^2$。 当以y缩放函数分析时，数据首次显示出对于初始核子动量值显著大于核物质费米动量（即$> 0.3$GeV/c）的情况下的缩放趋近。 显示英文摘要

摘要： Inclusive electron scattering is measured with 4.045 GeV incident beam energy from C, Fe and Au targets. The measured energy transfers and angles correspond to a kinematic range for Bjorken $x > 1$ and momentum transfers from $Q^2 = 1 - 7 (GeV/c)^2$. When analyzed in terms of the y-scaling function the data show for the first time an approach to scaling for values of the initial nucleon momenta significantly greater than the nuclear matter Fermi-momentum (i.e. $> 0.3$ GeV/c).
