    Abstract

    The evaluation of the 93Nb(n,n') 93mNb and 93mNb(n,2n) 92mNb reactions cross-sections important for reactor dosimetry was carried out by means of Pade-approximation. The experimental data bases comprise the results of cross-sections measurements performed up to January 1993. The preliminary analysis of experimental cross-sections has been made. The evaluated cross-sections are presented in an analytical form convenient for the use in applications. The files of evaluated cross-sections (File 3) and covariances (Files 30 and 33) in the ENDF-VI format were prepared. The comparison of evaluations from this work and IRDF-90 was performed.
