In the first part of this paper we reply to Michel Paty's critical remarks on our paper "Einstein and the Compton effect". We state that we did not evaluate Einstein's response to the experimental evidence about the light quantum hypothesis beyond 1923. Nevertheless, in the second part we analyze two important experiments completed in 1924: those performed by Bothe and Geiger in Germany and by Compton and Simon in the United States. We point out that both experiments provided additional evidence that supported Einstein's views about the quantum theory of radiation. Nonetheless, we contend that even after becoming aware of these results, Einstein never expressed a categorical judgment about the reality of light quanta, such as the one stated by De Broglie as early as 1923, with which we compared Einstein's position.Downloads
