Study of delayed neutron decay curves from thermal neutron induced fission of U and Pu

The results of measurements of the delayed neutron decay curves obtained from the thermal neutron induced fission of ²³⁵U and ²³⁹Pu are presented. The data were obtained by the periodical irradiation method on the pulsed reactor IBR-2 during the time interval 5 to 730 msec following irradiation. A comparison of these newly measured decay curves with the curves calculated using several standard delayed neutron sets was then performed. Based on these measurements, a new 7-group delayed neutron model is proposed.
