Cavendish Laboratory
In 1929, with the benefit of an Aitchison travelling scholarship from the University of Melbourne, Massey went to Trinity College, Cambridge to perform research at the Cavendish Laboratory led by Ernest Rutherford. The scholarship expired after two years, but he was awarded an 1851 Exhibition Scholarship in 1931. At this time the Cavendish Laboratory was one of the leading centres of physics in the world. In 1932 Cavendish laboratory scientists John Cockcroft and Ernest Walton split the atomic nucleus, James Chadwick discovered the neutron, and Patrick Blackett and Giuseppe Occhialini confirmed the existence of the positron.
