C256300100008 INSTITUTE (1USAWAU) C256300100009 METHOD (COINC) Detection of delayed fission and half life C256300100010 determinations were made by a direct electronic C256300100011 measurement of the elapsed time between arrival of a C256300100012 burst of particles at the target and the time of C256300100013 fission decay. The time distribution of fission C256300100014 events is determined by using fast signals from a C256300100015 semiconductor fission detector, and a signal from the C256300100016 cyclotron oscillator or Van de Graaff beam chopper to C256300100017 start and stop, respectively a time-to-amplitude C256300100018 converter.
