| Summary, etc |
This study has been carried out to compile and to find the best production way to<br/>produce 67Cu by comparing the cross-section data of different charged particle induced<br/>reactions (induced by p, d,3He and α) on natNi, Zn, and Ga targets. The radioisotope 67Cu<br/>has long been known to be the ideal properties for treating the disease, especially cancer.<br/>The lower beta-emitter, with a half-life of 2.6 days, has excellent chemical properties that<br/>can be used as a radioimmunotherapy. We have studied total twenty reactions for the<br/>production of 67Cu; namely 64Ni(α,p)67Cu,natZn(p,x)67Cu, natZn(d,x)67Cu, 67Zn(d,2p) 67Cu,<br/>68Zn(γ,p) 67Cu, 68Zn(p,2p)67Cu, 68Zn(p,2p)67Cu, 68Zn(d,3He)67Cu, 68Zn(α,x)67Cu, 70Zn(p,<br/>α)67Cu,70Zn(d,x) 67Cu, 69Ga(p,3p) 67Cu and 71Ga(p,x)67Cu 64Cu(α,2p)67Cu and 66Cu(n,<br/>γ)67Cu,67Zn(n,p)67Cu,68Zn(n,d) 67Cu,68Zn(n,x)67Cu, 69Ga(n,n+a) 67Cu reactions. Out of<br/>which we have selected total twelve reaction on account of their suitablity to use in<br/>diagonostic and therapeutic applications; namely 64Ni(α,p)67Cu, natZn(p,x)67Cu,<br/>natZn(d,x)67Cu, 67Zn(d,2p) 67Cu, 68Zn(γ,p) 67Cu, 68Zn(p,2p)67Cu, 68Zn(p,2p)67Cu,<br/>68Zn(d,3He)67Cu, 68Zn(α,x)67Cu, 70Zn(p,α)67Cu,70Zn(d,x) 67Cu, 69Ga(p,3p)67Cu reactions.<br/>The 64Cu(α,2p)67Cu and 66Cu (n, γ)67Cu reactions are not suitable because the radio<br/>isotopic impurities cannot be separated chemically from the final product. The given<br/>neutron induced reactions 67Zn(n,p)67Cu,68Zn(n, d) 67Cu,68Zn(n,x)67Cu 69Ga(n,n+a) 67Cu<br/>also not suitable for the production of 67Cu because they give product at higher energy<br/>which are not reliable of their use in diagonostic and therapeutic applications. For<br/>medical Application we use prefer those reactions which gives higher cross-section at<br/>low energy cyclotron. The experimantal data for all the selected reactions were taken<br/>from IAEA on line data source EXFOR. For comparison the excitation function of all<br/>selected reactions was plotted using ORIGN software. By using their experimental<br/>information reliability of the data was checked with each other and based on their Qvalues and threshold. From above given reactions two reactions 64Ni(α, p)67Cu and<br/>68Zn(p,2p)67Cu are looking more reliable to produce 67Cu. In these reactions the energy is<br/>low, and cross-section is high; so, they can be conveniently produced within the hospital<br/>using low energy cyclotrons. Experimental data of selected charged particle induced<br/>reactions were critically analysed and compared to achieve best production route for 67Cu <br/>Finally we suggested 64Ni (α, p)67Cu reaction as the best reaction because of its higher<br/>yield at low energies |
