Abstract :An experiment based on photonuclear reaction was performed to measure half-life and study the gamma -transitions for scandium nucleus with bremsstrahlung photons of 18 MeV end point energy, generated by a clinical linear accelerator. These photons were used to irradiate scandium sample. The HPGe detector calibration for before and after counting was carried using standard point sources and a volume source. For analysis of results and spectrum gf3 and ROOT package was used. As a result of this experiment 45 Sc( γ ,n) 44 Sc gamma-ray energies, associated errors and half-life value of 44 Sc from ground state were calculated and found in agreement with the published literature values.
