利用碳、铁和铅与一个或多个质子和零个介子的末态强子系统的荷电ν_{μ}相互作用，研究了核环境对类弹性相互作用的影响.基于领先质子的运动学，重建了转移到靶核的四动量平方Q^{2}，并首次在单个实验中测量了微分截面与Q^{2}以及铁、铅和碳与闪烁体的截面比。测量结果显示出对原子序数的依赖性。虽然类准弹性散射碳是兼容的预测，铁和铅的散射所表现出的趋势有利于预测与强子的核内再散射占一个传统的粒子级联处理。这些测量有助于区分中微子振荡实验中使用的初始态核子和末态相互作用的不同模型。
Charged-current ν_{μ} interactions on carbon, iron, and lead with a final state hadronic system of one or more protons with zero mesons are used to investigate the influence of the nuclear environment on quasielasticlike interactions. The transferred four-momentum squared to the target nucleus, Q^{2}, is reconstructed based on the kinematics of the leading proton, and differential cross sections versus Q^{2} and the cross-section ratios of iron, lead, and carbon to scintillator are measured for the first time in a single experiment. The measurements show a dependence on the atomic number. While the quasielasticlike scattering on carbon is compatible with predictions, the trends exhibited by scattering on iron and lead favor a prediction with intranuclear rescattering of hadrons accounted for by a conventional particle cascade treatment. These measurements help discriminate between different models of both initial state nucleons and final state interactions used in the neutrino oscillation experiments.
