Abstract
The photoelectric emission from clean molybdenum surfaces has been measured as a function of the angle of incidence and state of polarization of monochromatic irradiation. For polarization perpendicular to the plane of incidence, the photocurrent decreased monotonically with increasing angle of incidence. For parallel polarization, the photocurrent increased with increasing angle to values at 75° that were as much as 40 times that at normal incidence. No spectral dependence of the effect was detected within the narrow range of ultraviolet wavelengths available. This is apparently the same as the vectorial effect studied by Ives in more complex emitting systems. It cannot be related directly to the power absorbed from the incident beam; its variation resembles that of the energy stored in the radiation field within the metal and near its surface. Possible interpretations of this observation are discussed.
