Abstract

Relative abundances and periods of delayed neutrons have been measured by the method based on periodic irradiation of 237Np sample by neutrons generated from T(p,n) reaction and measurements of delayed neutron activities. The measured data are given in the six group presentation.

Keywords
the relative yield of delayed neutron, half-life predecessors, the time dependence of the intensity of the delayed neutrons, 4π-detector, constants for short-lived groups.
