Abstract : The feasibility of measuring thermal neutron absorption cross section from the results of first-order reactor perturbation theory was investigated. Techniques were developed for this measurement utilizing the AGN-201 reactor of the U. S. Naval Postgraduate School. These techniques were evaluated by measurement of the thermal absorption cross section of indium using gold-197 as a standard. The result obtained was 194.4 plus or minus 2.3 barns. A comparison with the most recently published value of this cross section, 196 plus or minus 5 barns, demonstrates the feasibility of the method for obtaining improved precision for the measurement of the cross sections of selected materials.
