    Investigation of some even-even selenium isotopes within the interacting boson model-2
    (Versita, 2008) Böyükata, Mahmut; Uluer, Ihsan
    The even-even Selenium isotopes in the A similar to 80 mass region and the general features of its structure have been investigated within the framework of the interacting boson model-2. The neutron proton version of the model has been applied to the Se (A=74 to 80) isotopes with emphasis on the description of the 0(1)(+), 2(1)(+), 0(2)(+), 2(2)(+), and 4(1)(+) states. The energy levels, B(E2)and B(M1)electromagnetic transition probabilities were calculated. The results of these calculations were compared with previous experimental results and were shown to be in good agreement.

    Investigation of The Multipolarity of Electromagnetic Transitions in 88, 90Kr Nuclei
    (Tubitak Scientific & Technological Research Council Turkey, 2006) Turkan, Nurettin; Olgun, Davut; Uluer, Ihsan; Inan, Sait
    We have determined the most appropriate Hamiltonian that is needed for present calculations of nuclei about the A congruent to 80 region by the view of Interacting Boson Model-2(IBM-2).After obtaining the best Hamiltonian parameters, level energies and B( E2) probabilities of some transitions in (88, 90) Kr nuclei were estimated. Results are compared with previous experimental and theoretical data and it is observed that they are in good agreement. Finally, R-1 = B( E2; 4(1) -> 2(1))/B( E2; 2(1) -> 0(1)), R-2 = B( E2; 2(2) -> 2(1))/B( E2; 2(1) -> 0(1)), R-3 = B( E2; 0(2) -> 2(1))/B( E2; 2(1) -> 0(1)), R-4 = B( E2; 2(2) -> 0(1))/B( E2; 2(2) -> 2(1)), R-5 = B( E2; 3(1) -> 2(1))/B( E2; 3(1) -> 4(1)), R-6 = B( E2; 4(2) -> 4(1))/B( E2; 4(2) -> 2(2)), and R-7 = B( E2; 4(1) -> 2(1))/B( E2; 2(2) -> 2(1)), ratios are compared with the values of dynamic symmetry limits.
