The aim of my research, however, is related to study the production cross section of medically important radionuclides. Both the diagnostic and therapeutic radioisotopes are interesting to work with PET is one the most modern technique for diagnostic in nuclear medicine. A comprehensive literature survey identified that charged particle induced reaction data base needs enormous work in the direction of evaluation of cross section data for the production and use of PET radionuclides.73Se is a radioisotope of selenium with known decay and structure properties. Its production has been studied but assessment of all production routes has never been done. Due to this gap in research, this isotope has been recommended for clinical use. In this study, assessment of cross section data will be done. The comparison of experimental and theoretical results may lead to the recommended cross section data for yield calculation.enThesis
