| Abstract: | Excitation functions were calculated by the code TALYS for 10 proton-induced reactions on 100Mo. For 100Mo(p,d+pn)99Mo and 100Mo(p,2n)99mTc, calculations were also performed using the code STAPRE. Furthermore, for those two reactions and natMo(p,x)96Tc, evaluation of available experimental data was also carried out. The production of 99mTc via the 100Mo(p,2n)-process is discussed. The ratio of atoms of long-lived 99gTc and 98Tc to those of 99mTc is appreciably higher in cyclotron production than in generator production of 99mTc; this may adversely affect the preparation of 99mTc-chelates. |
