Abstract: We carried out neutron interferometry measurements to determine the coherent neutron scattering lengths of gaseous natural krypton and 86Kr. Measurements were performed at a 250 kW TRIGA reactor. The accuracy of the results is restricted by the stability of the set-up and not by the limited neutron flux. The results obtained at this reactor prove that neutron interferometry is feasible even at small neutron sources, provided that a stable set-up is used.
