Excitation functions were measured for the [sup 45]Sc([ital n],2[ital n])[sup 44]Sc[sup [ital m]], [sup 45]Sc([ital n],2[ital n])[sup 44]Sc[sup [ital m]+[ital g]], and [sup 55]Mn([ital n],2[ital n])[sup 54]Mn reactions from threshold to 13 MeV, and for the [sup 45]Sc([ital n],[ital p])[sup 45]Ca, [sup 45]Sc([ital n],[alpha])[sup 42]K, [sup 55]Mn([ital n],[ital p])[sup 55]Cr, and [sup 55]Mn([ital n],[alpha])[sup 52]V reactions over the neutron energy range of 6 to 13 MeV. The quasimonoenergetic neutrons were produced via the [sup 2]H([ital d],[ital n])[sup 3]He reaction using a deuterium gas target at a variable energy compact cyclotron. The activation technique in combination with high resolution [gamma]-ray spectroscopy was used. In the case of the [sup 45]Sc([ital n],[ital p])[sup 45]Ca and [sup 55]Mn([ital n],[ital p])[sup 55]Cr reaction produces, low-level'' [beta][sup [minus]] counting was applied. The reaction product [sup 45]Ca was separated radiochemically prior to [beta][sup [minus]] counting. Statistical model calculations taking into account precompound effects were performed for all the reactions studied. The experimental excitation functions are reproduced well by the calculation except for the ([ital n],[alpha]) reaction on the [sup 45]Sc target.
