The temperature coefficient of the resonance integral for uranium metal and oxide has been measured over a wide temperature range for rods with different diameters. The activation method was used and the 106 kev γ ray following the N239 decay was measured with a pulse-height analyzer. The resonance integral has been expressed as a linear function of The following approximate relations have been found. , The results have been compared with calculated values published elsewhere. The experimental values lie lower than most theoretical ones, but in several cases there is agreement within the common limits of error.
