Theoretical calculations of double differential neutron emission cross-sections for 116, 118, 124sn nuclei induced by protons at intermediate energy

Monte Carlo is a useful method that is not being able to solve analytically, involves uncertain parameters, enables to solve complex systems and quantitative problems and provides their numerical samples. Especially in the field of nuclear and particle physics and medical physics applications, high cost of designing and analyzing experiments, detector designing and in many different areas, it has become an indispensable tool for physicists. Using Monte Carlo techniques, besides its applications, is important to determine the investigated particle at a certain energy level in which angles or at an angle and in which level of energy it is going to react.Differential and total scattering cross sections are widely used in experimental studies of atoms and subatomic physics. Scattering cross section is used to relate the scattering angle which is formed by the collision of a particle with a force field of a particle in the other. The equations which are used to derive differential cross section can be used in the laboratories to establish the relationship between the measurable and immeasurable quantities. A lot of information about the structure of the particles which are proton, neutron and electron, and atomic and subatomic particles can be obtained by the bombardment. The methods used in scattering problems are based on the particle`s energy which is previously given, except in cases of energy conditions of a given particle in the potential area.Recently, heavy nuclei double differential cross sections (DDX) applications gained importance. As the number of patients admitted for treatment of cancer with heavy ions, the risk of secondary cancer produced and developed by radiation has become a serious problem. The problem here is that during the heavy ion treatment, radiation produced by the reaction is given in high doses as well as to the other organs which are out of the treatment. In order to assess the risk of second cancers in heavy-ion cancer therapy, it is essential to evaluate the neutron-production double differential cross sections from heavy-ion interactions. (Satoh et al., 2011).This study includes the theoretical calculations of the double differential cross sections in the angles of 15°, 20°, 30°, 45°, 60°, 75°, 95°, 105°, 120°, 135°, 140° which are all belong to the excitation energy protons 10.19 MeV, 10.20 MeV, 10.72 MeV, 10.74 MeV, 11.14 MeV, 11.16 MeV and 14 MeV and 116, 118, 124Sn nuclei (p,n) reaction. The calculated cross sections and the experimental cross sections were compared and showned to be compatible with each other.
