Method and apparatus for computing nuclear reaction cross section and path integral in particle transport, and device

Abstract

The present application discloses a method and apparatus for computing a nuclear reaction cross section and a path integral in particle transport, an electronic device, and a storage medium. The method includes: obtaining a product of a macroscopic nuclear reaction cross section of a material and an additional function by using a linear combination of basis functions; and obtaining a path integral of the product of the macroscopic nuclear reaction cross section of the material and the additional function by using the linear combination of basis functions. The additional function is a function of spatial position and energy, where the domain of the function is a set of points in space and a set of non-negative real number energy, and the range of the function is complex numbers or vectors of the complex numbers. Embodiments disclosed in the present application provide a supplementary computation method for a situation where an additional function appears or multi-group cross sections are used in computing a nuclear reaction cross section and a path integral in particle transport by using a linear combination of basis functions.
