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.
