چکیده [English]

The excitation functions of natAg(p,n)109Cd, natAg(d,2n)109Cd, natIn(p,pxn)109In®109Cd, natCd(p,pxn)109Cd and natPd(α,xn)109Cd reactions for 109Cd production were calculated using ALICE-91 code. The required thickness of the target was obtained by SRIM code for each reaction. The production yield of cadmium-109 was calculated by considering the excitation functions. The heat transfer of the target in each above mentioned nuclear reaction was investigated. The optimum reaction for production of 109Cd by accelerators was determined.
