“…* corresponding author; e-mail: radon@ifd.uni.wroc.pl An attempt to approach the explanation was made for a tungsten field emitter [18] and confirmed by the results obtained for a tantalum field emitter [19]. All the results containing such photocurrent oscillations are reviewed taking into consideration the new interpretation.…”

This paper contains a short reconsideration and explanation of the effect of photofield emission-current deviations. Theoretical considerations of the dynamic image-potential barrier did not yield a satisfactory result. A certain interpretation, suggested a few years ago, indicated that the photocurrent deviations reflect quantum-well states of the outer microcrystal of the apex of the field emitter. This point of view covers a variety of photocurrent deviations observed both for the integral field emission and for the one from a single crystal face as well as from a barium covered field emitter. It also includes the deviations observed for different photon energies and the deviations containing different apparent frequencies.
