Abstract:
In this project, proton induced reactions on Calcium isotopes have been studied. The main
objective of the study is to understand and investigate the pre-compound and compound nuclear
reaction mechanisms of proton induced reaction cross sections on Calcium isotopes (44Ca, and
48Ca) within the energy range of Proton from 5 MeV-100 MeV. The theoretical cross section of
the four reaction channels: 44Ca (p, n) 44Sc, 44Ca (p, 2n) 43Sc, 48Ca (p, n) 48Sc and 48Ca (p, 2n)
47Sc have been calculated using the semi- Classical model computer code COMPLET by
including both the compound and pre-Compound nucleus reaction. The theoretical results are
compared with the experimental excitation functions obtained from EXFOR data source, IAEA.
The study shows that high energy parts of excitation functions are dominated by pre-equilibrium
reaction mechanism whereas the low energy parts are dominated by compound nucleus reaction
mechanism. Therefore the incident proton energy increases the pre-compound reaction is more
significant than compound reaction. Both pre-compound and compound theoretical cross section
compared with experimental cross section by the help of Pearson’s correlation coefficient it has
strong positive correlation
