Numerical simulation of the differential scattering cross sections of very cold neutrons by the infinite solid circular cylinder

The given work continues to develop a technique of definition the parameters for the inhomogeneities in non-uniform environments by means of very cold neutrons (VCN). In the work the differential scattering cross sections of VCN by the infinite solid circular cylinder are given. They were calculated in the first Born’s approximation and based on the construction of the exact decision of the equation of Shrödinger by a method of division of variables. We compare the values of the differential scattering cross sections, calculated by these methods, for the various velocity of VCN, for the test sample – a cylinder with a radius 25 nm and optical nuclear potential 1,81*10(-7)eV.
