HALF-LIVES OF 47Sc ISOTOPE FROM PHOTONUCLEAR REACTIONS

Abstract

Abstract. In order to understand atomic nuclei, photonuclear reaction is an important tool. Photons are used to induce the reactions. The use of bremsstrahlung photons generated from a medical linear accelerator is practical for performing these types of reactions. In this study, the 18 MeV endpoint energy bremsstrahlung photons have been used for activating a titanium target. By analyzing the gamma spectrum, the half-life of the 47 Sc isotope has been determined to be 3.5626 days. The result is very close to the present literature values of 3.3492 days.
