Abstract
A dedicated facility far gamma-gamma coincidence studies of (n,gamma) reactions at thermal neutron energies is described. The facility and t he adopted method of data acquisition make it possible to determine in tensities of two step gamma cascades proceeding from the neutron captu ring slate to a set of selected low-lying levels via resolved and unre solved intermediate levels occurring between the neutron capturing sta te and a final level of interest. A detailed description of the method for accumulating the gamma-ray spectra, characterizing these two-step cascades, is given including procedures for corrections of these spec tra for various kinds of backgrounds and distortions.
