A study on the excitation functions of 60,62Ni(?,n), 60,61Ni(?,2n), 58,64Ni(?,p), natNi(?,x) reactions

The prediction of nuclear cross-section data is crucial, especially in the absence of experimental data or in the difficulty of these experimental data. Nickel (Ni) is an important material in fusion and fission reactor technologies, the production of radionuclides in nuclear medicine, and many other fields. In this study, the excitation functions for 60,62Ni(?,n), 60,61Ni(?,2n), 58,64Ni(?,p), and natNi(?,x) reactions have been investigated by using pre-equilibrium reaction models. The calculations of the excitation functions for the reactions are used with the geometry-dependent hybrid model in ALICE/ASH code and the two-component exciton model in TALYS 1.8 code. The obtained results are compared to each other, and the experimental data are taken from the EXFOR database. © 2018, Shanghai Institute of Applied Physics, Chinese Academy of Sciences, Chinese Nuclear Society, Science Press China and Springer Nature Singapore Pte Ltd

Investigation of neutron and proton distributions of He, Li, and Be isotopes using the new Skyrme-Force parameters

The proton and neutron densities, root-mean-square (rms) radii of proton density and neutron density, and neutron skin thickness of 4-10 He, 6-11 Li, and 7-12 Be isotopes are calculated using Skyrme-Hartree-Fock method with SLy4, SLy5, SLy6, and SLy7 force parameters. The evaluated results are compared with experimental data. Also, the results of halo nuclei ( 6,8 He, 11 Li, and 11 Be) are compared with the results of other isotopes for selected nuclei having the same neutron configuration. © Pleiades Publishing, Ltd., 2010

The Investigation of Radionuclide Concentrations in Soil and Lifetime Cancer Risk Due to Gamma Radioactivity in Zonguldak, Turkey

The distributions of ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs activity concentrations were determined using a high-purity germanium detector in uncultivated surface soil samples collected from Zonguldak. The range of ²²⁶Ra, ²³²Th, ⁴⁰K and ¹³⁷Cs activity concentrations varied from 10.5 ± 2.0 to 98.0 ± 4.3 Bq kg¯¹ (mean value 28.8± 4 Bq kg¯¹), from 12.9 ± 3.4 to 53.2 ± 5.1 Bq kg¯¹ (mean value 29.6± 3 Bq kg¯¹), from 190 ± 22 to 808 ± 43 Bq kg¯¹ (mean value 395± 31 Bq kg¯¹) and from <0.5 to 47.1± 3.8 Bq kg¯¹ (mean value 12.5± 2 Bq kg¯¹), respectively. In addition, the mean outdoor absorbed dose rates in air (terrestrial, terrestrial+cosmic), annual effective dose equivalent, radium equivalent activity and external hazard index were found to be 48 nGy h¯¹ (terrestrial), 56 nGy h¯¹ (terrestrial+cosmic), 58 μSv y¯¹, 101 Bq kg¯¹ and 0.27, respectively. The evaluated excess lifetime cancer risks (ELCRs) varied from 0.13× 10¯³ to 0.36× 10¯³ with a mean value of 0.20× 10¯³
