Abstract

The photoelectric yields of small silicate and graphite grains are calculated as a function of incident photon wavelength for the purpose of modeling interstellar grains. The large surface-to-volume ratio of a small grain is expected to result in an increased photoelectric yield when compared with a bulk sample of the same material. The ratio of grain yield to bulk yield is calculated from the Mie solution for the fields inside a spherical particle and from assumptions regarding the electron emission process. Absolute photoelectron yields are calculated from published bulk yields for wavelengths of 900–1500 Å. Results are presented for grain radii of 100 and 1000 Å. These results should be useful for future investigations of photoelectric emission from interstellar grains.
