“…It results in an average electric field which is added to the macroscopic field [3,4]. However, these studies do not consider the microscopic influence of ion bound states which can induce several processes involving exchange of one or more electrons between an ion and a metallic surface [5]: resonant neutralization and ionization, Auger de-excitation and neutralization. These effects can change the local intensity of the electronic current in the arc spot on the cathode.…”

“…Actually, the interaction between an ion and a metallic surface leads to various processes involving simultaneously one or more electrons of the conduction band: resonant capture in which one electron is captured from the conduction band onto a bound state of the ion; resonant ionization which is the reverse process; and Auger capture or ionization which involves at least two electrons (e.g. one is captured while the other is excited in the conduction band) [4]. If a sufficiently high electric field is applied, the process of capture onto a bound state of an ion may be followed by a tunnelling process with a probability large enough to produce outward electrons which contribute significantly to the electronic current.…”
