| Title | Letter from [Joseph John] Thomson, Holmleigh, West Road, Cambridge, to Mr [Alan Archibald Campbell] Swinton, 66 Victoria [Street], London, S.W. |
| Creator | Thomson; Sir; Joseph John (1856 - 1940); physicist |
| Date | 2 June 1907 |
| Description | Believes that the momentum of the canal strahlen would per particle be most likely between 40 or 50 times that of the cathode rays. Supposes that the kintic energy would be about the same for each, commenting that 'this would make the momenta proportional to the square roots of the masses'. |
