Pauli letter collection: letter to Werner Heisenberg

Pauli replies to questions from Heisenberg in his letter of 4 November 1934. The self-energy of the electron in Pauli's theory becomes logarithmically infinite . This theory can only be developed with Bose-statistics. He writes about the Lagrange function of the scattering of light by light and about the magnetic moment of the neutron and the symmetry of the laws of nature with regard to the sign of the charge. He talks about the magnetic moment of the proton and the deuteron.
