报告了阿波罗 14 号和阿波罗 15 号尘埃样品的低能电子发射的光电产率、二次电子产率和能量分布，光子能量为 4 至 21 eV，入射电子能量为 50 至 2500 eV。推导了太阳辐照引起的微分光电子通量和能量分布谱，并将结果用于估计月球光电子鞘层的电特性。描述了对月球尘埃样品元素成分的俄歇电子能谱分析，并与阿波罗15号指挥服务舱在月球轨道上进行的S-161 X射线荧光实验获得的结果进行了比较。结果与细粒（主要是绝缘）粉末的预期结果一致。
The photoelectric yield, secondary electron yield and energy distribution of low energy electron emission from Apollo 14 and 15 dust samples are reported for photon energies, 4 to 21 eV, and incident electron energies, 50 to 2500 eV. The differential photoelectron flux and energy distribution spectrum due to solar irradiation are derived, and the results are used to estimate the electrical characteristics of the lunar photoelectron sheath. Auger electron spectroscopic analysis of the elemental composition of the lunar dust samples is described, and a comparison is made with the results obtained by the S-161 X-ray fluorescence experiment on-board the Apollo 15 Command Service Module, while in lunar orbit. The results are consistent with those expected for a finegrain, predominantly insulating, powder.
