    Determination of the effects of nuclear level density parameters on photofission cross sections of U-235 up to 20 MeV
    (E D P Sciences, 2017) Sarpun, Ismail Hakki; Aydin, Abdullah; Pekdogan, Hakan
    The level density models and level density parameters are two of important quantities for describing the properties of nuclei. Especially, the level density parameter has an important role as input in calculation of reaction cross sections. In this study, the cross sections on U-235(g,f) reaction were calculated for different level density models using the TALYS 1.6 code up to 20MeV gamma incident energies. First, it was determined the level density model that was the closest to the experimental data. Secondly, cross sections obtained for different level density parameters of this model were compared with experimental data from the EXFOR database. Thus it was determined the best level density parameter fit to experimental data.

    Nuclear model calculations on the production of 125,123Xe and 133,131,129,128Ba radioisotopes
    (Maik Nauka/Interperiodica/Springer, 2012) Aydin, Abdullah; Pekdogan, Hakan; Tel, Eyüp; Kaplan, Abdullah
    In this study, production rates of Xe-125,Xe-123 and Ba-133,Ba-131,Ba-129,Ba-128 medical isotopes produced by I-127(p, 3n)Xe-125, I-127(p, 5n)Xe-123, Cs-133(p, n)Ba-133mg, Cs-133(p, 3n)Ba-131mg, Cs-133(p, 5n)Ba-129, and Cs-133(p, 6n)Ba-128 reactions have been investigated up to 100 MeV incident proton energy. The pre-equilibrium calculations involve the hybrid model, the geometry-dependent hybrid model and the cascade exciton model. The calculated results are compared with the experimental data taken from the literature.
