Production cross–section calculations of medical 32P, 117Sn, 153Sm and 186,188Re radionuclides used in bone pain palliation treatment

In this study, production cross–section calculations of 32P, 117Sn, 153Sm and 186,188Re radionuclides used in bone pain palliation treatment produced by 30Si(d,γ)32P, 118Sn(γ,n)117Sn, 116Sn(n,γ)117Sn, 150Nd(α,n)153Sm, 154Sm(n,2n)153Sm, 152Sm(n,γ)153Sm, 186W(d,2n)186Re, 187Re(γ,n)186Re, 185Re(n,γ)186Re and 187Re(n,γ)188Re reactions have been investigated in the different incident energy range of 0.003–34 MeV. Two-component exciton and generalised superfluid models of the TALYS 1.6 and exciton and generalised superfluid models of the EMPIRE 3.1 computer codes have been used to pre-equilibrium (PEQ) reaction calculations. The calculated production cross–section results have been compared with available experimental results existing in the experimental nuclear reaction database (EXFOR). Except the 118Sn(γ,n)117Sn, 150Nd(α,n)153Sm and 185Re(n,γ)186Re reactions, the two-component exciton model calculations of TALYS 1.6 code exhibit generally good agreement with the experimental measurements for all reactions used in this present study.

Theoretical study of deuteron induced reactions on 6,7Li, 9Be and 19F targets

The nuclear reactions of the deuteron particles with light nuclei have been extensively investigated in the history of nuclear physics. In this work, the cross-sections of deuteron reactions 6Li(d,n)7Be, 6Li(d,t)5Li, 7Li(d,2n)7Be, 7Li(d,p)8Li, 7Li(d,t)6Li, 9Be(d,p)10Be, 9Be(d,t)8Be, 19F(d,n)20Ne and 19F(d,p)20F were studied for the investigation of structural fusion materials. Excitation functions of these reactions were determined by using ALICE-ASH code considering equilibrium (EQ) and pre-equilibrium (PEQ) effects. The calculated cross-sections, experimental results and TENDL-2011 library data are presented in graphical form.

Calculation of excitation functions for the production of Cu and Co medical isotopes

Copper and cobalt radioisotopes have been used for both diagnostic and therapeutic purposes in the field of nuclear medicine. There is considerable interest in 60 ,61,64,67Cu and 55,57Co radioisotopes for some applications like PET, SPECT imaging and targeted radiotherapy of tumors. In present study, the production of 60,61,64,67Cu and 55,57Co via 64Zn(p,α)61Cu, 67Zn(p,α)64Cu, 70Zn(p,α)67Cu, 58Ni(p,α)55Co, 60Ni(p,α)57Co, 64Zn(p,nα)6°Cu and 68Zn(p,nα)64Cu reactions have been investigated in the range of 5–40 MeV proton incident energy. The new version of the code ALICE-2011 is used to determine the excitation functions of these nuclear reactions. The calculated excitation functions were compared with experimental results and semi-empirical cross section values of a previously developed model.

Spallation neutron emission spectra in medium and heavy target nuclei by a proton beam up to 140 MeV energy

In this study, neutron-emission spectra produced by (p,xn) reactions for some spallation neutron target nuclei such as (65)Cu, (204,206,207,208)Pb, (209)Bi, (232)Th and (238)U have been calculated by a proton beam up to 140 MeV. Multiple pre-equilibrium mean free path constants from internal transition for (204,208)Pb (p, xn) neutron emission spectra have been investigated. In the calculations, pre-equilibrium effects were calculated by using new evaluated hybrid model and geometry dependent hybrid model, full exciton model and cascade exciton model. The reaction equilibrium component was calculated by Weisskopf-Ewing model. The obtained results have been discussed and compared with the available experimental data and found agreement with each other.
