Paul Marmet; (20 May 1932 – 20 May 2005) was a Canadian physicist and professor, best known for developing, along with his mentor Larkin Kerwin, a high resolution electron selector for the study of electronic states of negative ions.
This instrument, along with a mass spectrometer he developed, was widely used by scientists for electron scattering studies which led to the discovery of enhanced vibrational excitation in nitrogen, and for the study of free radicals.
