Excitation Function Of Alpha Induced Reaction On Isotopes Of Zinc ( 64zn, 68zn, 70zn) With Alpha Energy Below 50 Mev

Abstract

In this thesis alpha induced reactions on stable isotopes of Zinc for energies of alpha below 50MeV were studied. Experimentally measured excitation function obtained from EXFOR data source IAEA, for the isotopes 64 30Zn(α, p)67 31Ga, 68 30Zn(α, n)71 32Ge, 64 30Zn(α, n + p)66 31Ga, 70 30Zn(α, p)73 31Ga and 68 30Zn(α,3n)69 32Ge were used to compare with the theoretical calculation for understanding how well the calculation able to admit the experiment providing a theoretical explanation of the excitation functions based on the COMPLET code calculation was the major objective of the thesis. For the theoretical calculation the COMPLET code has been employed. The level density parameter(k) was varied to get good agreement between the theoretical and measured data. The COMPLET code for both compound nuclear reactions and pre-equilibrium reactions. The relation-ships of alpha-energy and reaction cross-section have been plotted as excitation functions and the correlation was explained. The result shows relatively higher energy parts of excitation functions are dominated by pre-equilibrium reaction mechanism, whereas the low energy parts are dominated by compound nucleus reaction mechanism. When the incident alpha energy increases the pre-equilibrium reaction is more significant. The experimental excitation function agrees well with the theoretical calculations in most of the energy region. The thesis may raise interest and could be a resource for further study on excitation function of alpha induced reaction on Zinc stable isotopes.
