The Emission of Positive Ions from Heated Metals

Abstract

The positive ion emission from iron, nickel, copper, rhodium, columbium, platinum, uranium and thorium has been studied. In addition to the emission of singly charged atoms of the alkalies, reported by others, it is found that iron, nickel, copper, rhodium and columbium emit singly charged atoms of their own metals. The results from rhodium and columbium are in agreement with those already reported by H. B.Wahlin.
