his important work was cathode ray experiment . he also discovere the natural radioactivity of pottassium.In his second experiment, he investigated whether or not the rays could be deflected by an electric field.in the third experiment he measured the mass to charge ratio of cathode rays by measuring how much they are deflected and how much energy they carries.
he discovery of the electron and of isotopes, and the invention of the mass spectrometer.
