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 ⁴⁵Sc(γ,n)⁴⁴Sc gamma-ray energies, associated errors and half-life value
of ⁴⁴Sc from ground state were calculated and found in agreement
with the published literature values.
