Abstract
In the analysis of a sample of 1424 stars produced in nuclear emulsion by 20 GeV/c protons, 107 stars are found to contain short dense tracks, which have been interpreted as due to nuclear fission. The mean range and velocity of the fission fragments are estimated to be ~9.9 μ and ~0.047 c respectively, compared with ~4.8 μ and ~0.026 c respectively for the residual recoils of ordinary stars. The average space angle between the products of binary fission is found to be 128°.
