Incoming links: The collisions of neutrons with nitrogen nuclei by Norman Feather
Norman Feather Created 2026-10-18 Updated 2026-11-05
An experimental nuclear physicist who studied collisions of neutrons with nitrogen nuclei in 1932. Tracks in an expansion cloud chamber revealed both recoils and disintegration events, allowing charged reaction products to expose an otherwise invisible neutral projectile. The experiment established a concrete route to studying nuclear reactions initiated by neutrons.[ref]
