Investigations of Production Cross Sections and Induced Activity of 94,95,96,98Tc Produced in Mo Target by 30 MeV Proton Beam

Abstract

Theoretical models often fill significant gap exists in measured data and radioisotopes produced may be used in research, medical and safely disposal of radioactive waste. The excitation functions of ⁹⁴Mo(p,n)⁹⁴Tc, ⁹⁵Mo(p,n)⁹⁵Tc, ⁹⁶Mo(p,n)⁹⁶Tc and ⁹⁸Mo(p,n)⁹⁸Tc reactions were investigated using nuclear reaction model codes TALYS-1.95 and EMPIRE-3.2.3 from reaction threshold to 30 MeV. These codes incorporate three major nuclear reaction mechanisms including direct, compound and pre-compound nuclear reactions. Theoretical results obtained from TALYS-1.95 and EMPIRE-3.2.3 codes were compared with existing literature data and found to be in reasonable agreement. Additionally, induced radioactivity estimation is also conducted for a thick Mo target due to the primary interaction of 1μA, 30 MeV proton beam.
