Precise modeling of neutrino interactions on nuclear targets is essential for neutrino oscillations experiments. The modeling of the energy of final state particles in quasielastic (QE) scattering and resonance production on bound nucleons requires knowledge of both the removal energy of the initial state bound nucleon as well as the average Coulomb and nuclear optical potentials for final state leptons and hadrons. We extract the average values of the real part of the nuclear optical potential for final state nucleons (\(U_{opt}^{QE}\)) as a function of the nucleon kinetic energy from inclusive electron scattering data on nuclear targets (\(_\mathbf{6 }^\mathbf{12 }{} \mathbf{C} \)+\(_\mathbf{8 }^\mathbf{16 }{} \mathbf{O} \), \(_\mathbf{20 }^\mathbf{40 }{} \mathbf{Ca} \)+\(_\mathbf{18 }^\mathbf{40 }{} \mathbf{Ar} \), \(_\mathbf{3 }^\mathbf{6 }{} \mathbf{Li} \), \(_\mathbf{18 }^\mathbf{27 }{} \mathbf{Al} \), \(_\mathbf{26 }^\mathbf{56 }{} \mathbf{Fe} \), \(_\mathbf{82 }^\mathbf{208 }{} \mathbf{Pb} \)) in the QE region and compare to calculations. We also extract values of the average of the real part of the nuclear optical potential for a \(\varDelta (1232)\) resonance in the final state (\(U^\varDelta _{opt}\)) within the impulse approximation. We find that \(U^\varDelta _{opt}\) is more negative than \(U_{opt}^{QE}\) with \(U^\varDelta _{opt}\approx \)1.5 \(U_{opt}^{QE}\) for \(_\mathbf{6 }^\mathbf{12 }{} \mathbf{C} \).

核子和$$ \ varDelta $$Δ共振的光势比较

中微子在核目标上相互作用的精确模型对于中微子振荡实验至关重要。在准弹性（QE）散射和结合核子上产生共振的过程中，对最终态粒子能量的建模需要了解初始态结合核子的去除能以及最终态轻子和强子的平均库仑和核光学势。 。我们提取最终状态核子核光学势（的实部的平均值\（U_ {选择} ^ {QE} \）作为从核打击目标包括电子散射数据核子动能的函数（）\ （_ \ mathbf {6} ^ \ mathbf {12} {} \ mathbf {C} \） + \（_ \ mathbf {8} ^ \ mathbf {16} {} \ mathbf {O} \），\（_ \ mathbf {20} ^ \ mathbf {40} {} \ mathbf {Ca} \） + \（_ \ mathbf {18} ^ \ mathbf {40} {} \ mathbf {Ar} \），\（ _ \ mathbf {3} ^ \ mathbf {6} {} \ mathbf {Li} \），\（_ \ mathbf {18} ^ \ mathbf {27} {} \ mathbf {Al} \），\（_ \ QE地区的mathbf {26} ^ \ mathbf {56} {} \ mathbf {Fe} \），\（_ \ mathbf {82} ^ \ mathbf {208} {} \ mathbf {Pb} \））并进行比较计算。我们还提取了脉冲近似中最终状态（\（U ^ \ varDelta _ {opt} \））的\（\ varDelta（1232）\）共振的核光学势的实部平均值的值。。我们发现\（U ^ \ varDelta _ {opt} \）比\（U_ {opt} ^ {QE} \）更负与\（U ^ \ varDelta _ {选择} \约\） 1.5  \（U_ {选择} ^ {QE} \）为\（_ \ mathbf {6} ^ \ mathbf {12} {} \ mathbf {C} \）。
