Abstract
Development of technology of isotope production at an electron accelerator, in particular 47Sc by the 48Ti(γ,p)47Sc reaction, requires accurate data on cross-sections of this and other photo-proton reactions on the titanium isotopes, as the available data are characterized by considerable scatter. A simple technique for estimating maximum and width of the excitation function of a reaction with dominating giant dipole resonance was proposed and validated earlier. The method is based on measurement of normalized reaction yield in a thin target, overlapping completely a flux of X-rays, and processing of data obtained with the use of a developed analytical model. The joint activation of foils from natural nickel, molybdenum and titanium by bremsstrahlung radiation with end-point photon energy in the range 40…95 MeV was carried out. The characteristics of the reactions 48Тi(γ,p)47Sc, 49Ti(γ,p)48Sc, 50Ti(γ,np)48Sc, 47Ti(γ,p)46Sc, and 48Ti(γ,np)46Sc are studied by new technique. For verifying results, the wellexamined 58Ni(γ,n)57Ni and 100Mo(γ,n)99Mo reactions, taking place in the nickel and molybdenum foils, are used.
