The Speed of Positive Ions in Nitrogen

摘要: In a previous paper from this laboratory it was suggested that when helium ions move under the influence of an electric field through gas, positive charge carried by ion does not remain long associated with single atom, but is repeatedly passed on to atom at collision process electron capture. This may be regarded as equivalent increase in target area presented atoms and must therefore lead reduction their mobility. When foreign given gas conditions resonance necessary for capture would normally occur. If absence mobility found afford unambiguous measure its mass, we expect value itself less than predicted owing operation process. From study number various gases now know satisfactory which demonstrate effect. Even simple like Rb+, Cs+, In+, Tl+ size has profound effect mobility, so fact He+ more slowly much heavier sodium cannot definitely attributed exchange The hypothesis offers very probable, certain, explanation relatively low ions.
