标题： Difference of surface effects in the inclusive (p, p'x) and (d, d'x) reactions

摘要： 先前的研究揭示了包括$(n, n'x)$和$(p, p'x)$反应中的表面效应。 这些发现对核数据评价的改进做出了重要贡献。 然而，包括$(d, d'x)$反应中的表面效应几乎未被研究。 本研究的目的是研究$(p, p'x)$和$(d, d'x)$反应中表面效应的差异。 我们还旨在阐明这种差异的来源。 $(p, p'x)$和$(d, d'x)$反应的能量谱及其径向分布是通过一步半经典畸变波模型计算的。 在小能量转移区域，$(d, d'x)$反应的能量谱径向分布比$(p, p'x)$反应更倾向于核的外区。 此外，忽略核吸收的计算表明，两种反应的径向分布几乎相同。 $(d, d'x)$反应中的表面效应比$(p, p'x)$反应更明显。 差异的一个主要原因是氘核比质子更容易被核吸收。 显示英文摘要

摘要： Previous studies have revealed surface effects in inclusive $(n, n'x)$ and $(p, p'x)$ reactions. These findings have contributed significantly to the improvement of nuclear data evaluation. However, surface effect in inclusive $(d, d'x)$ reaction has hardly been investigated. The purpose of this study is to investigate the difference of the surface effects in the $(p, p'x)$ and $(d, d'x)$ reactions. We also aim to clarify the origin of the difference. The energy spectra and their radial distributions for the $(p, p'x)$ and $(d, d'x)$ reactions are calculated by the one-step semiclassical distorted wave model. In the region with small energy transfer, the radial distribution of the energy spectra for the $(d, d'x)$ reaction is found to be shifted toward the outer region of the nucleus more than that of the $(p, p'x)$ reaction. Furthermore, the calculations ignoring the nuclear absorption show that the radial distributions in the two reactions are nearly identical. The surface effect in the $(d, d'x)$ reaction is more pronounced than in the $(p, p'x)$ reaction. A significant cause of the difference is that deuteron undergoes stronger absorption by the nucleus than proton.
