When z is a real negative, the integral in Eq. must be intended in the Cauchy principal value sense. This is related to the fact that the line arg z=π represents a branch cut for the exponential integral function .

It should be noted that in the original paper, Pauli used the opposite convention; i. e., the temporal factor had the form exp(+iωt). For this reason, the subsequent formulas are the complex conjugate of those written in .

We use, as far as possible, a notation similar to the original one adopted in .

If, on the contrary, the illumination produces no geometrical shadow, to obtain a regular representation also at the second reflection, it is sufficient to change φ into φ−2πn in all the following equations.
