Description

The existing keV neutron capture cross section data of the stable Ir isotopes 191 and 193 exhibit large discrepancies and have never been published in their final versions. Therefore, the stellar cross sections of these isotopes have been remeasured relative to that of gold by means of the activation method. Metallic samples were irradiated in a quasi-stellar neutron spectrum for kT=25 keV using the 7Li(p,n)7Be reaction near threshold. The resulting stellar cross sections of 191Ir and 193Ir show uncertainties of 4 and 7 percent, respectively. (orig.)
