本文报道了水(H2O)的弯曲(010)和未分辨伸缩(100+001)振动量子的电子碰撞激发的绝对微分截面(DCSs)的综合研究。在6-20 eV范围内研究了8个入射电子能量(E0)，散射电子角范围为10°-135°。利用分子相移分析技术从相应的振动DCS得到积分截面(ICSS)。考虑了这些振动ICS的自洽，在每个E0处，将它们与可用的弹性ICS和电离ICS相加，以提供H2O总截面(GTS)的估计，然后可以与Szmytkowski(1987化学)的独立GTS进行核对。太棒了。让我们来吧。136 363)和Sueoka et al(1986 J.Phys.B：在。摩尔。太棒了。19 L373)。通常情况下，双方都达成了良好的共识。
A comprehensive study of absolute differential cross sections (DCSs) for electron impact excitation of the bending (010) and unresolved stretching (100 + 001) vibrational quanta of water (H2O) is reported. Eight incident electron energies (E0) in the range 6-20 eV were investigated, and the scattered electron angular range was 10°-135°. Integral cross sections (ICSs) were derived from the corresponding vibrational DCSs using a molecular phase shift analysis technique. The self-consistency of these vibrational ICSs was considered by summing them, at each E0, with available elastic and ionization ICS to provide estimates for the H2O grand total cross section (GTS), which could then be checked against the independent GTSs of Szmytkowski (1987 Chem. Phys. Lett. 136 363) and Sueoka et al (1986 J. Phys. B: At. Mol. Phys. 19 L373). Good agreement was typically found.
