Investigation of e0-electron yield on the distance from the point of radioactivedecay arising to the surface in 64Cu sources

Abstract

Near-zero energy electron yield 0 Ye from the sources with different thickness in radioactive decay 64Cu were measured. Yield of e0-electrons sharply increases for the sources with small thickness of 64Cu and can be qualitatively described by 0 Ye ~ r−2 – dependence, where r – distance from charge location to the surface of source.
