Excitation functions were measured for the {sup 46}Ti({ital n},{ital p}){sup 46}Sc{sup {ital m}} and {sup 46}Ti({ital n},{ital p}){sup 46}Sc{sup {ital m}+{ital g}} reactions over the neutron energy range of 5.4 to 10.5 MeV. Use was made of the activation technique in combination with high-resolution {gamma}-ray spectroscopy. From the available experimental data isomeric cross-section ratios ({sigma}{sub {ital m}}/({sigma}{sub {ital m}}+{sigma}{sub {ital g}})) were determined. Statistical-model calculations taking into account precompound effects were performed for fast neutron-induced reactions on {sup 46}Ti. The calculational results agree well with the experimental data on emitted proton spectra as well as on the excitation functions of various reaction channels. The calculated cross section for the formation of the isomeric state ({sigma}{sub {ital m}}) is strongly dependent on the input level scheme of the product nucleus; the same effect is reflected in the calculation of the isomeric cross-section ratio.
