fourth approximation (in the one-electrone theory). However, Pauli does not expect all
divergences to vanish, because the usual theory gives rise to logarithmic divergences in
terms proportional to l 4 even in the one-electrone theory. – Yes, it is about what the
situation is right now.
Prof. Pauli lectures about meson theory, although rather elementary still quite instructive,
and there are seminars once or twice aweek. But to be admitted to the institution
library here is quite an enterprise (which Fröberg probably can testify), and it is impossible
to get keys. Pauli hoped by the way that Fröberg would soon complete his work
from here. Otherwise I am doing more or less well here, but weather has not turned out
particularly southern – last Saturday it was snowing, and the inside temperature is like
that at least in my room.
How are you doing yourself now, and how is it otherwise in Lund There have not
been any sensational changes, I presume.
Finally, I beg you to forward my greetings to Mrs. Gustafson, and, of course, you have
to give my regards to all members of the Department,
Yours faithfully, Bertil Nilsson.
P. S. I send you my proofs at the same time; I suppose that it suffices (in order
not to change the text too much) to write in the first paragraph “. . . some parts of the
self-energy . . . were made to disappear . . . ” (or something similar) without approaching
the details too closely, which, of course, ought to be known to a person who might want
to read my paper. It might further be adequate [with] the lines that I added at the end;
otherwise you may just erase them,
P.S.S. I was to late to the post office with this (12 November) after a class by Pauli,
so it will take more time before I can send it.
