Adjustment of Non-linear Interaction Parameters for Relativistic Mean Field Approach by Using Artificial Neural Networks
Bayram, T.; Akkoyun, S.; Senturk, S. (PLEIADES PUBLISHING INC, 2018)The relativistic mean field (RMF) model with a small number of adjusted parameters has been used successfully in the last thirty years for predictions of various ground-state nuclear properties of nuclei. In this model, ... -
An artificial neural network application on nuclear charge radii
Akkoyun, S.; Bayram, T.; Kara, S. O.; Sinan, A. (IOP PUBLISHING LTD, 2013)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. ... -
Energy Levels and Half-Lives of Gallium Isotopes Obtained by Photo-Nuclear Reaction
Dulger, F.; Akkoyun, S.; Bayram, T.; Dapo, H.; Boztosun, I. (IOP PUBLISHING LTD, 2015)We have run an experiment to determine the energy levels and half-lives of Gallium nucleus by using the photonuclear reactions with end-point energy of 18 MeV bremsstrahlung photons, produced by a clinical linear accelerator. ... -

Senyigit, M.; Atac, A.; Akkoyun, S.; Kaskas, A.; Bazzacco, D.; Nyberg, J.; Recchia, F.; Brambilla, S.; Camera, F.; Crespi, F. C. L.; Farnea, E.; Giaz, A.; Gottardo, A.; Kempley, R.; Ljungvall, J.; Mengoni, D.; Michelagnoli, C.; Million, B.; Palacz, M.; Pellegri, L.; Riboldi, S.; Sahin, E.; Soderstrom, P. A.; Dobon, J. J. Valiente (ELSEVIER SCIENCE BV, 2014)gamma Rays and neutrons, emitted following spontaneous fission of Cf-252, were measured in an AGATA experiment performed at INFN Laboratori Nazionali di Legnaro in Italy. The setup consisted of four AGATA triple cluster ... -
Photonuclear Reaction Cross Sections for Gallium Isotopes
Akkoyun, S.; Bayram, T.; Kara, S. O. (IOP PUBLISHING LTD, 2015)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 ... -
Response of AGATA segmented HPGe detectors to gamma rays up to 15.1 MeV
Crespi, F. C. L.; Avigo, R.; Camera, F.; Akkoyun, S.; Atac, A.; Bazzacco, D.; Bellato, M.; Benzoni, G.; Blasi, N.; Bortolato, D.; Bottoni, S.; Bracco, A.; Brambilla, S.; Bruyneel, B.; Ceruti, S.; Ciemala, M.; Coelli, S.; Eberth, J.; Fanin, C.; Farnea, E.; Gadea, A.; Giaz, A.; Gottardo, A.; Hess, H.; Kmiecik, M.; Leoni, S.; Maj, A.; Mengoni, D.; Michelagnoli, C.; Million, B.; Montanari, D.; Nicolini, R.; Pellegri, L.; Recchia, F.; Reiter, P.; Riboldi, S.; Ur, C. A.; Vandone, V.; Valiente-Dobon, J. J.; Wieland, O.; Wiens, A. (ELSEVIER SCIENCE BV, 2013)The response of AGATA segmented HPGe detectors to gamma rays in the energy range 2-15 MeV was measured. The 15.1 MeV gamma rays were produced using the reaction d(B-11,n gamma)C-12 at E-beam=19.1 MeV, while gamma rays ... -
Time-of-flight discrimination between gamma-rays and neutrons by using artificial neural networks
Akkoyun, S. (PERGAMON-ELSEVIER SCIENCE LTD, 2013)In gamma-ray spectroscopy, a number of neutrons are emitted from the nuclei together with the gamma-rays. These neutrons influence gamma-ray spectra. An obvious method for discrimination between neutrons and gamma-rays is ...
