JUL 01, 1966

Multiparameter experiments simultaneously measure velocities of fission fragments and particles emitted by the deëxciting fragments. Semiconductor detectors make possible high‐resolution measurements.

NUCLEAR FISSION forms the basis of a large and expanding nuclear technology. At the same time, it is one of the most complex processes currently being investigated in the general field of low‐energy nuclear physics. Since a comprehensive theory does not exist, the burden of supplying the necessary fundamental information rests primarily with the experimentalist.
