    Investigation of ground state features of some medical radionuclides
    (Carl Hanser Verlag, 2012) Tel, Eyüp; Aydın, Abdullah; Kara, Ayhan; Kaplan, Abdullah
    In this study, ground state properties for some medical radionuclides used widely in medical applications have been investigated using Skyrme-Hartree-Fock (SHF) method. We calculated the proton, neutron and charge density RMS (root-mean-square) radii of some medical radionuclides such, as K-42 Ca-45, K-81, Rb-81, Rb-82, Sr-85, In-110, In-111, Cs-123, Tl-201 and (201)pb using the SHF calculations with the Skyrme force parameters. The calculated results are compared with the available experimental values for charge density RMS radii. The proton, neutron, charge and mass density distributions for all nuclei used in this study have also been calculated. The calculated conclusions can he used 'in estimating nuclear properties of the medical nuclei and for the calculations of pre-equilibrium reactions cross section data for the production of new medical radioisotopes.

    (E D P Sciences, 2015) Sahan, Halide; Tel, Eyyup; Sahan, Muhittin; Aydin, Abdullah; Sarpun, Ismail Hakki; Kara, Ayhan; Doner, Mesut
    Fusion has a practically limitless fuel supply and is attractive as an energy source. The main goal of fusion research is to construct and operate an energy generating system. Fusion researches also contains fusion structural materials used fusion reactors. Material issues are very important for development of fusion reactors. Therefore, a wide range of fusion structural materials have been considered for fusion energy applications. Zirconium (Zr), Niobium (Nb) and Tantalum (Ta) containing alloys are important structural materials for fusion reactors and many other fields. Naturally Zr includes the Zr-90 (%51.5), Zr-91 (%11.2), Zr-92 (%17.1), Zr-94 (%17.4), Zr-96 (%2.80) isotopes and Nb-93 and Ta-181 include the Nb-93 (%100) and Ta-181 (%99.98), respectively. In this study, the charge, mass, proton and neutron densities and the root-mean-square (rms) charge radii, rms nuclear mass radii, rms nuclear proton, and neutron radii have been calculated for Zr87-102, Nb-93,Ta-181 target nuclei isotopes by using the Hartree-Fock method with an effective Skyrme force with SKM*. The calculated results have been compared with those of the compiled experimental taken from Atomic Data and Nuclear Data Tables and theoretical values of other studies.
