The energy loss of proton beams in water vapor is analyzed with a full quantum-mechanical treatment, the distorted-wave model. This model takes into account distortion effects due to the long-range Coulomb potential. Projectile energies from 10 keV up to 1 MeV are considered. Mean stopping power and equilibrium charge-state fractions are calculated and compared with experimental data. The validity of Bragg's additivity rule is investigated.
利用全量子力学处理方法——扭曲波模型，分析了质子束在水蒸气中的能量损失。该模型考虑了长程库仑势引起的扭曲效应。考虑了从10 keV到1 MeV的入射粒子能量。计算了平均阻止本领和平衡电荷态分数，并与实验数据进行了比较。研究了布拉格加和规则的有效性。
