Abstract
The experimental results on delayed-neutron yields from thermal-neutron-induced fission of some actinides in the IBR-2 pulsed reactor are presented. A method of periodic irradiation without displacement of the sample was used. The measurements of delayed-neutron total yields in thermal-neutron-induced fission of 239Pu, 233U, and 237Np and in cold-neutron-induced fission of 235U, 233U, and 239Pu were carried out. All values were obtained with the use of the value of β0 for (n th+235U) as a reference. Precise measurements of decay curves in the time interval 5–350 ms for 235U and 239Pu were performed.
