k0- and Q0-factors of 18 short-lived nuclides used in reactor neutron activation analysis were determined using the Fast Irradiation and Measurement System (FIMS) of the TRIGA MARK II reactor at the Atominstitut der Österreichischen Universitäten. The Q0-factors were either critically selected from literature, or experimentally determined according to theCd-ratio method, while the k0-factors were additionally determined by theBare monitor method. A comparison is made with the values calculated by introduction of literature data for the input parameters. Moreover, a user oriented tabulation is presented of k0-, Q0-factors and related nuclear data. All results were critically tested with respect to their accuracy and precision.
