在Rosetta使命中，67 P/Churyumov-Gerasimenko彗星彗发中的[O I]谱线的发射是由电子碰撞离解水而不是光离解过程来解释的。这是电子诱导加工作用在这样的物体上已经看到的直接证据。其他发射功能的分析是一个障碍，缺乏详细的知识，电子碰撞截面，突出了需要广泛的电子散射数据从彗星上检测到的分子系统。在本文中，我们提出了一个概述的电子散射数据相关的观测在昏迷，稀薄的大气和表面上的67 P/Churyumov-Gerasimenko在罗塞塔使命的理解的需求。阐明电子作用的相关观测来自光谱、使用离子和电子传感器的粒子分析以及质谱测量。为了模拟这些过程，电子碰撞数据应整理和审查的电子散射数据库和一个例子中给出的BEAMD，这是一个更大的财团的虚拟原子和分子数据中心-VAMDC的一部分。
The emission of [O I] lines in the coma of Comet 67P/Churyumov-Gerasimenko during the Rosetta mission have been explained by electron impact dissociation of water rather than the process of photodissociation. This is the direct evidence for the role of electron induced processing has been seen on such a body. Analysis of other emission features is handicapped by a lack of detailed knowledge of electron impact cross sections which highlights the need for a broad range of electron scattering data from the molecular systems detected on the comet. In this paper, we present an overview of the needs for electron scattering data relevant for the understanding of observations in coma, the tenuous atmosphere and on the surface of 67P/Churyumov-Gerasimenko during the Rosetta mission. The relevant observations for elucidating the role of electrons come from optical spectra, particle analysis using the ion and electron sensors and mass spectrometry measurements. To model these processes electron impact data should be collated and reviewed in an electron scattering database and an example is given in the BEAMD, which is a part of a larger consortium of Virtual Atomic and Molecular Data Centre—VAMDC.
