Öğe An artificial neural network application on nuclear charge radii(IOP PUBLISHING LTD, 2013) Akkoyun, S.; Bayram, T.; Kara, S. O.; Sinan, A.Artificial neural networks (ANN) have emerged with successful applications in nuclear physics as well as in many fields of science in recent years. In this paper, ANN have been employed on experimental nuclear charge radii. Statistical modeling of nuclear charge radii using ANN are seen to be successful. Based on the outputs of ANN we have estimated a new simple mass-dependent nuclear charge radii formula. Also, the charge radii, binding energies and two-neutron separation energies of Sn isotopes have been calculated by implementation of a new estimated formula in Hartree-Fock-Bogoliubov calculations. The results of the study show that the new estimated formula is useful for describing nuclear charge radii.Öğe Consistent Empirical Physical Formulas for Potential Energy Curves of 38-66Ti Isotopes by Using Neural Networks(Pleiades Publishing Inc, 2013) Akkoyun, S.; Bayram, T.; Kara, S. O.; Yildiz, N.Nuclear shape transition has been actively studied in the past decade. In particular, the understanding of this phenomenon from a microscopic point of view is of great importance. Because of this reason, many works have been employed to investigate shape phase transition in nuclei within the relativistic and nonrelativistic mean field models by examining potential energy curves (PECs). In this paper, by using layered feed-forward neural networks (LFNNs), we have constructed consistent empirical physical formulas (EPFs) for the PECs of Ti38-66 calculated by the Hartree-Fock-Bogoliubov (HFB) method with SLy4 Skyrme forces. It has been seen that the PECs obtained by neural network method are compatible with those of HFB calculations.Öğe Photonuclear Reaction Cross Sections for Gallium Isotopes(IOP PUBLISHING LTD, 2015) Akkoyun, S.; Bayram, T.; Kara, S. O.The photon induced reactions which are named as photonuclear reactions have a great importance in many field of nuclear, radiation physics and related fields. The cross-sections of neutron (photo-neutron (gamma,xn)) and proton (photo-proton (gamma,xn)) productions after photon activation have been calculated by using TALYS 1.2 computer code in this study. The target nucleus has been considered gallium which has two stable isotopes, Ga-69 and Ga-71. Furthermore, the pre-equilibrium and compound process contributions to the total cross-section have been investigated.
