WebOct 1, 2024 · Francis William Aston (1877-1945) Thomson had already been awarded the Nobel Prize in Physics, in 1906, for his work in gas discharge tubes. He had correctly deduced that cathode rays were a stream of negatively charged sub-atomic particles – the electron. He then turned his attention to the simultaneously produced positive rays.
