Description

Czubek's method of measurement of the thermal neutron absorption cross section may be influenced by the energy spectrum of the thermal neutron flux (deviated from the Maxwellian distribution) which exist in the two-region geometric system. A correction function has been experimentally obtained to eliminate this disturbance. A series of reference measurements has been done on the H3BO3 solution and Plexiglas outer moderator. The obtained function allows to interpret correctly measurements of the thermal neutron absorption rate in the range from 10 000 to 45 000 s-1 for hydrogenous samples. (author)
