Nuclear model analysis and optimization of production data of the medically interesting Ga via alpha induced reactions on Cu targets.

Evaluation of the Cu(α,n)Ga, Cu(α,2n) Ga and Cu(α,n)Ga reactions was done to study the production of medical radionuclides Ga, Ga and Ga respectively. Cu(α,2n)Ga and Cu(α,3n)Ga reactions were also evaluated for the estimation of radioisotopic impurities. Cross section data of each reaction were compiled and normalized to the standard values of decay data and monitor reaction. To check the consistency of the literature data, three nuclear model calculations were performed, using nuclear model codes; TAYLS 1.9, ALICE-IPPE, and EMPIRE 3.2. A well-developed evaluation methodology based on the normalized experimental data and nuclear model calculations was used to generate the statistically fitted cross sections. From the fitted cross sections, thick target yields for each reaction were calculated for the estimation of radioisotopic impurities. Finally, a suitable energy region for the production of Ga, Ga and Ga was suggested with a minimum level of radioisotopic impurities.
