Abstract

We have measured the neutron-induced-fission cross section of the U235 isomer with cold and with thermal neutrons. Because of its short half-life (26 min), preparation of an adequate isomeric target is the major difficulty. A simple and easy-to-operate technique has been developed. The cross-section ratio of isomer to ground state is measured to be 1.61 0.44 and 2.470.45 for the cold and the thermal neutrons, respectively.
