Abstract
During some experiments involving the acceleration and subsequent retardation of positive ions of mercury we found that the retarding potential had to be twice as great as the accelerating potential in order to stop completely the flow of ions. Investigation showed that this was due to some ions being accelerated as doubly charged Hg
2+
ions and retarded as singly charged Hg
+
ions, the change of charge being due to the Hg
2+
ion capturing an electron from a neutral atom with which it collided in the space between the accelerating and retarding fields. Since this process of electron transfer in mercury vapour had not been previously studied in detail we modified the apparatus to enable it to be investigated.
