Pauli letter collection: letter to Homi J Bhabha

Pauli thanks Bhabha for his letter of the 26th March. He gives developments about meson and proton dispersion and comments on Bethe's latest work on meson theory and nuclear power and also his interpretation based on Fierz's study of Blau and Wambacher's results. Pauli sees a solution in new particles that have been observed in cosmic radiation. Heitlers theory seems to be unsatisfying. Pauli is working on a theory on high speed particles. He adds some remarks on the war and some physicists.
