Intercalibrated values of fission-spectrum-averaged cross sections have been obtained for the 24Mg (n,p),46 Ti (n,p), 54Fe (n,p), 5eFe (n,p), 58Ni (n,p), 59Co (n,α), 92Mo (n,p), and 115In (n,n') threshold reactions. All values are given relative to an assumed value of 0.61 mb for 27Al (n,α) 24Na. Irradiations were performed in a specially designed Converter Facility, located in a beam port near the thermal column of the Ispra-I Reactor. The converter is a disk of enriched uranium-aluminum alloy suspended in an essentially material-free cavity. Spectral purity correction factors were calculated using the Monte Carlo code TIMOC. The measured values are compared to the results of other workers.
