DETERMINATION OF PROMPT NEUTRON DECAY CONSTANTS OF MULTIPLYING SYSTEMS

Technical Report ·
OSTI ID:4325760
In a multiplying system below prompt critical, the noutron population in the absence of delayed prompt neutron precursors would decay as e/sup -at/ after a normal mode was established, where a is thae prompt neutron decay constant. This constant was measured by three different techniques: the pulsed neutron method, the Rossi alpha method, and a related method originally devised by Feyman to measure the mean square number of neutrons emitted per thermal fission.
