All the while he was very active in the international nuclear arms control movement. 140 x 1945 235 U n 95 y Nuclear fission. This phenomenon is produced by neutron bombardment of uranium235. A slow neutron captured by U-235 results in the highly unstable compound nucleus U-236, which ruptures into a heavy fragment and a light fragment.
