    Description of Exotic Nuclei with the Interacting Boson Model
    (Amer Inst Physics, 2008) Boyukata, M.; Van Isacker, P.; Uluer, I.
    Even-even nuclei in the A similar to 100 mass region are investigated within the framework of the interacting boson model-1 (IBM-1). The study includes energy spectra and electric quadrupole transition properties of zirconium, molybdenum, ruthenium and palladium isotopes with neutron number N >= 54. A global parametrization of the IBM-1 hamiltonian is found leading to a description of 301 collective levels in 30 nuclei with a root-mean-square deviation from the observed level energies of 119 keV The geometric character of the nuclei can be visualized by plotting the potential energy surface V(beta, gamma) obtained from the IBM-1 hamiltonian in the classical limit. The parametrization established on the basis of known elements is then used to predict properties of the unknown. neutron-rich isotopes Zr-106, (MO)-M-112, Ru-116 and Pd-120.

    The Effect of the Deformation Parameter on the Cross Sections for Reactions: Pd-110(d,n)Ag-111 and Pd-110(d, 2n)(110m) Ag
    (Maik Nauka/Interperiodica/Springer, 2018) Boyukata, M.; Sarpun, I. H.; Aydin, A.
    In this study, we focused on the effects of the deformation parameter on the cross sections. First, the deformation parameters of target nucleus Pd-110 was determined within the interacting boson model (IBM). Later this parameter was used in the TALYS-1.8 code to calculate the cross sections of the Pd-110(d,n)Ag-111 and Pd-110(d, 2n)(110m) Ag reactions. Moreover, other deformation parameters obtained RIPL-3 and TALYS default were used for the cross section calculation. The calculated results were compared with the experimental nuclear reaction data from EXFOR.

    Odd nuclei and shape phase transitions: the role of the unpaired fermion
    (World Scientific Publ Co Pte Ltd, 2011) Fortunato, L.; Alonso, C. E.; Arias, J. M.; Boyukata, M.; Vitturi, A.
    Shape phase transitions in even and odd systems are reviewed within the frameworks of the Interacting Boson Model(IBM) and the Interacting Boson Fermion Model(IBFM), respectively and compared with geometric models when available. We discuss, in particular, the case of an odd j = 3/2 particle coupled to an even-even boson core that undergoes a transition from the spherical limit U(5) to the gamma-unstable limit O(6). Energy spectrum and electromagnetic transitions, in correspondence of the critical point, display behaviors qualitatively similar to those of the even core and they agree qualitatively with the model based on the E(5/4) boson-fermion symmetry. We describe then the U-BF(5) to SUBF(3) transition when a fermion is allowed to occupy the orbits j = 1/2, 3/2,5/2. The additional particle characterizes the properties at the critical points in finite quantum systems.
