Abstract

Because of the importance of using ^99mTc isotope as a radioactive tracer for nuclear medicine, the production of this isotope from accelerating protons at energies 1-70 MeV is investigated carefully through the evaluation of the calculated excitation functions of the ¹⁰⁰Mo(p,2n)^99mTc reaction. For accuracy, the proton interaction channels with ¹⁰⁰Mo, the excitation functions of reactions,¹⁰⁰Mo(p,2n)^99mTc, ¹⁰⁰Mo (p, pn)⁹⁹Mo, and ¹⁰⁰Mo (p, nonelastic) are calculated, using Kalbach Systematic approach in Exciton model gathered with Feshbach-Kerman-Koonin (FKK) statistical theory. The results are compared with the available published data in the experimental nuclear reaction data (EXFOR) version of November 2022. The comparisons show acceptable results for the maximum cross-section of producing ^99mTc at 16 MeV protons. Also, rare data was searched for the reactions, ¹⁰⁰Mo (p, p n)⁹⁹Mo, and ¹⁰⁰Mo (p, nonelastic), to compare the present calculated results.
