Description

Experimental data and an analysis of delayed neutron decay curves in the time range 5-730 ms following irradiation of 235U and 239Pu are presented. The statistical accuracy is 0.3-0.4% for a time channel of 1 ms. Experimental data were compared with 6- and 8-group calculated data. The 7-group constant sets were proposed as most suitable for the description of the experimental curves. (author)
