WebDr Helen Chadwick completed her MChem at the University of Oxford in 2008, and her DPhil in Physical Chemistry in 2012. She received an EPSRC doctoral prize to continue her research as a post-doc in Oxford, before moving to the EPFL in Switzerland in 2013 to perform gas-surface dynamics experiments. WebApr 6, 2024 · In his experiment, Chadwick bombarded beryllium atoms with high-energy alpha particles. He observed that some new particles are emitted which carry no charge, and the mass of this particle is the same as that of protons. A neutron is usually represented as “n” and its charge is zero.
