| Summary, etc |
The radionuclides have wide range of applications in medical, agricultural, industrial,<br/>archaeology and research fields. Extensive research is being done on the production of<br/>medically used radionuclides due to their vast applications. This work includes<br/>compilation and evaluation of experimental nuclear reaction cross-section to produce<br/>72As. 72As has a half-life of 26 hours and it is used in PET and SPECT techniques. The<br/>main purpose of this work is to study about the cross-section data evaluation for the<br/>non-generator based production of 72As. These cross-section data evaluations will be<br/>related to charge particle (proton, deuteron and alpha) induced reaction on isotope of<br/>gallium (Ga), germanium (Ge), and Selenium (Se). The production data related to 72As<br/>is available in the form of data libraries of IAEA in EXFORE. To check the accuracy<br/>of the experimental data normalization of experimental reported data was done by using<br/>standard monitor reaction and decay data. Furthermore, nuclear model calculations<br/>were performed using theoretical nuclear model codes, EMPIRE, TENDL-2015 and<br/>ALICE-IPPE, to compare the experimental and theoretical data. In this work the<br/>reactions namely 69Ga(α,n)72As, 71Ga(α,3n)72As, 71Ga(3He,2n)72As, natGe(p,x)72As,<br/>natGe(d,x)72As, 70Ge(α,n+p)72As, 70Ge(α,x)72As, 72Ge(p,n)72As, 72Ge(α,x)72As,<br/>73Ge(p,2n)72As, 74Ge(p,3n)72As, natSe(p,x)72As, 74Se(p,x)72As, 74Se(α,x)72As,<br/>76Se(p,n+α)72As, and 76Se(p,x)72As were considered. After the compilation of this work<br/>we will check that except for generator based production routes which production route<br/>is suitable and can give yield with minimum impurities level. |
