WebSir John Sealy Edward Townsend, FRS [1] (7 June 1868 – 16 February 1957) was an Irish-British mathematical physicist who conducted various studies concerning the electrical conduction of gases (concerning the kinetics of electrons and ions) and directly measured the electrical charge. He was a Wykeham Professor of physics at Oxford University. [2] WebMay 25, 2024 · The first attempts at deriving electron scattering cross sections from swarm transport coefficients were made in the 1920s by Mayer , Ramsauer and Townsend et al .
