We report on measurements of photo-nuclear cross-sections which lead to the production of isotopes which are of interest in medical diagnosis and treatment sciences. Precise measurements of the cross sections of 48Ti (γ, p), 48Ti (γ, n), 48Ti (γ, pn), 48Ti (γ, 2n), 48Ti (γ,alpha), 197Au (γ, n) and 197Au (γ, pn) were made at gamma ray energies between 22 -27 MeV. The High Intensity Gamma Ray Source (HIγS) of Triangle Universities Nuclear Laboratory (TUNL), a Compton γ-ray facility employing a high intensity Free-Electron Laser (FEL) produced the gamma ray beams for the study. The activity of the reaction products was measured at TUNL’s low-background counting facility using High Purity Germanium detectors (HPGe). Lifetime data were fitted to obtain the isotope yields. Cross-section data are compared to calculations and other known available measurements, such as photo-nuclear cross sections of gold (Au) isotopes. This study reports on the techniques, methods, and results obtained from this measurement.
