Determination of K-Li Sub-Shell, Total K-L and Total K-M shell Vacancy Transfer Probabilities for Europium, Gadolinium and Terbium Akman, Ferdi; Durak, Rıdvan; Kaçal, Mustafa Recep; Turhan, Mehmet Fatih There are different ways to produce a vacancy in an atom such as photoelectric effect, Compton scattering, triplet production, charged particle Coulomb interaction, internal conversion, electron capture, positron annihilation and Auger effect. If an atom is bombarded with photons, electrons or protons which have enough energy for the ionization, the shell electron leaves the electronic cloud and the atom loses an electron through creation of a vacancy. The vacancy is filled either by emission of an X-ray, by Auger transition or Coster-Kronig transition which is special case of the Auger transition. These transitions are called radiative and non-radiative processes, respectively. In this work, to obtain the K-Li (i=2,3), total K-L and total K-M shell vacancy transfer probabilities for Europium, Gadolinium and Terbium elements, the experimental values of Kα1, Kα2, Kβ'1 and Kβ'2 X-ray production cross sections, K shell fluorescence yields and Kβ/Kα, Kα2/Kα1 and Kβ'1/ Kα1 intensity ratios were determined at 59.54 keV photon energy from a 100 mCi Am241 annular source using excitation geometry and a Si(Li) detector system. The experimental results were compared with theoretical values of Hartree-Slater and Hartree-Fock and other available experimental results.

Why Do We Need Nuclear Energy in Turkey? Araz, Aslı; Akdemir, Fatma; Akman, Ferdi; Durak, Rıdvan Nuclear energy is the energy in the nucleus, or core, of an atom. This energy can be released as heat from a chain reaction in a radioactive element such as uranium. Although Turkey has rich uranium reserves, Turkey has had plans for establishing nuclear power generation since the early 1960s. Today, plans for nuclear power are a key aspect of the country's aim for economic growth. In this study, nuclear energy current situation in Turkey is examined in terms of its scientific, social and economic aspects. Does that mean strength for a country to have a nuclear power plants? What does society think about nuclear power plants? Based on these two questions, the necessity of nuclear energy in a country is questioned and is examined whether is social benefits. It is discussed taking into account the effects on the environment of nuclear power plants and is presented solutions for it.

Experimental values of K to Li sub-shell, K to L, and K to M shell vacancy transfer probabilities for some rare earth elements Akman, Ferdi The K to Li (i=2,3), K to L, and K to M shell vacancy transfer probabilities for La, Ce, Pr, Nd, Sm, Eu, Gd, Tb, Dy and Er were determined at 59.54 keV using a reflection geometry. The measurements were performed using an 241Am annular radioactive source and a high resolution Si(Li) detector. The experimental results were compared with the theoretical values of Hartree-Slater and Hartree-Fock theories, semi-empirical and other available experimental results in the literature. Reasonable agreement is observed between the measured and theoretical results.

Measurement of L3 Sub-Shell to M, N, O Shell Radiative Vacancy Transfer Probabilities for Ho, Lu and Hg Elements Turhan, Mehmet Fatih; Akman, Ferdi; Kaçal, Mustafa Recep; Durak, Rıdvan The radiative vacancy transfer probabilities from L3 sub-shell to M, N, O sub-shells were measured for the elements Ho, Lu and Hg. To obtain related parameters, we used 59.54 keV gamma photons of 241Am radioactive source. Emitted L X-ray photons from targets were collected by means of a Si(Li) detector with resolution of 160 eV at 5.9 keV. The present results are generally in a good agreement with theoretical calculations and the other results obtained in the literature, within their range considering experimental uncertainty.
