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>.<The collisions of neutrons with nitrogen nuclei by Norman Feather>[Introduction, cloud-chamber apparatus and analysis of disintegration tracks]{ref}
