The quantum effect on the Wigner time-delay and distribution for the polarization scattering in a semiclassical dense plasma is explored. The partial wave analysis is applied for a partially ionized dense plasma to derive the phase shift for the polarization interaction. The Wigner time-delay and the Wigner distribution are derived for the electron-atom polarization interaction including the effects of quantum-mechanical characteristic and plasma screening. In this work, we show that the Wigner time-delay and the Wigner distribution for the polarization interaction can be suppressed by the quantum effect. The Wigner time-delay and the Wigner distribution are also significantly suppressed by the increase of plasma shielding. The variation of the Wigner time-delay and the Wigner distribution function due to quantum screening is discussed.
研究了半经典稠密等离子体中极化散射的维格纳时间延迟和分布的量子效应。将分波分析应用于部分电离的稠密等离子体，以推导极化相互作用的相移。推导了包括量子力学特性和等离子体屏蔽效应的电子 - 原子极化相互作用的维格纳时间延迟和维格纳分布。在这项工作中，我们表明极化相互作用的维格纳时间延迟和维格纳分布可以被量子效应抑制。等离子体屏蔽的增加也显著抑制了维格纳时间延迟和维格纳分布。讨论了由于量子屏蔽导致的维格纳时间延迟和维格纳分布函数的变化。
