Abstract
A new method of determination of the thermal neutron macroscopic absorption cross-section Sigma a for small samples has been checked experimentally. The measurements have been performed with spherical geometry by the pulsed method. Two samples (aqueous solutions of boric acid) with known values of the absorption cross-section have been used. Good agreement of the measured values of Sigma a with the known ones has been observed.Keywords
