Transfer of energy from electrons to atoms

Abstract

In the preceding paper(1) we have assumed that the electric dipole induced in an atom by a passing electron has the value corresponding to a static field which is equal to the instantaneous field of the electron. This is, however, not quite exact. Due to the rapid variation of the field there will be some sort of a time lag. The deflections will therefore be smaller than calculated in section A of preceding paper. But the most important result of the more rigorous calculation is that it yields an approximation to the transfer of energy which escaped our attention while we were using the approximation method A in the mentioned publication.(1)
