Abstract

The present work was done on alpha induced reaction mechanics on two natural coppers isotopes for the energy range of 15 to 30 Mev were investigated. The reaction channels for the total cross section 63Cu (α, n) 66Ga, 65Cu (α, 2n)67Ga, 63Cu(α, pn) 65Cu and 65Cu(α, n)68Ga were studied. The experimental data of reaction cross section COMPLETE code have been used. The aim study was compared experimental and theoretical reaction cross section both compound and pre-compound reaction and know the property, the reaction mechanism of the projectile particle reacts with target nuclei. The theoretical result was obtained from international atomic energy agency, exchange format data source. We understood the reaction mechanisms and the property of fragment particles during the reaction. Level density parameter and exaction number were varied to become good agreement between the calculated and measured data. In this study different dependency reaction cross section, the projectile energy was observed between the production of 67Ga and 65Zn. In alpha induced reaction with copper isotopes 66Ga, 67Ga, 68Ga and 65Zn are produced. Normally the calculation using a COMPLET code provides good outcome for the reaction cross-section of alpha induced reaction on low projectile energy. During the study of the reaction compound and pre-equilibrium reaction are occurred but direct reaction was almost not expected. Direct reaction is required to very large amount of energy.

Highlights

The study of nuclear reaction induced by alpha particle has been got significance result for reaction cross section [1]
The present work we discussed that alpha induced reaction on the natural coppers isotopes for the energy range of 15-50Mev.The quantitative earlier experimental cross section date were reported from IAEA, EXFOR data center
The projectile energy is measured in mega electron volt (Mev) whereas the cross section is measured in mill barn

Summary

Introduction

The study of nuclear reaction induced by alpha particle has been got significance result for reaction cross section [1]. Nuclear reaction refers to the process of producing new nuclei and elementary particles as particles and nuclei interact [3]. This is why accurate measurement and calculation of the cross section of nuclear reactions, and understanding of nuclear reaction mechanisms, is important. A large number of heavy mass-particle emitting radionuclides that were synthesized artificially were characterized Their half-lives vary widely, but the-particle energies are usually between 4 and 7 MeV [16]. The energy of alpha particles obtained from natural radioactive nuclei is dispersed to all parts and discrete in nature, and it is significantly smaller than the coulomb barrier, making it unfit for nuclear reactions [19]
