论文摘要
多弹性电子散射$（e，e'）$的横截面的计算很大程度上取决于筛选核库仑电位的筛选以及在核心附近的输入和即将到来的电子的波浪功能的变形。这些横截面以低于$ 10^{ - 30} $ cm $^2 $的值评估，根据模型，该截面因几个数量级而异。需要实验测量来限制模型，但是测量这种低横截面是一个真正的挑战。在这项研究中，我们证明了非弹性电子散射是$^{181} $ ta靶的主要核激发机制，该靶标被用新的强烈的10-30 keV电子束照射，该keV电子束带有偏置激光 - 上皮。计算表明，通过检测转换电子，应该可以测量核激发产率。量化了电子束加热和血浆沉积对触觉目标的影响，从而使可能的实验构型首次在此能量范围内研究$（E，E'）$过程。
Calculations of the cross sections of inelastic electron scattering $(e,e')$ on a nucleus in the multi-keV energy range strongly depend on the description of the screening of the nuclear Coulomb potential as well as on the deformation of the wave functions of the incoming and outgoing electron in the vicinity of the nucleus. These cross sections are evaluated at values lower than $10^{-30}$ cm$^2$ which vary by several orders of magnitude according to the models. Experimental measurements would be required to constrain the models but it is a real challenge to measure such low cross sections. In this study, we demonstrate that inelastic electron scattering is the main nuclear excitation mechanism in a $^{181}$Ta target irradiated with a new intense 10 - 30 keV electron beam produced with a biased laser-plasma. Calculations show that through the detection of conversion electrons, it should be possible to measure the nuclear excitation yields. The effect of electron beam heating and of plasma deposition on the tantalum target are quantified, thus allowing the dimensioning of a possible experimental configuration to study $(e,e')$ processes in this range of energy for the first time.
