Benchmarking Monte Carlo Simulations of Thermal Neutron Kinetics and Differential Die-away Analysis
Differential Die-Away Analysis (DDAA) is a very effective technique for detection of special nuclear material (SNM). It is based on fission neutrons that are detected with a time constant characteristic of the thermal neutron that created them. The presence of fast neutrons with this slow die-away time is a positive indication of the presence of SNM in the inspected cargo. Results are presented...
متن کاملDetermining neutron-capture cross sections via the surrogate reaction technique
Indirect methods play an important role in the determination of nuclear reaction cross sections that are hard to measure directly. In this paper we investigate the feasibility of using the so-called surrogate method to extract neutron-capture cross sections for low energy compound-nuclear reactions in spherical and near-spherical nuclei. We present the surrogate method and develop a statistical...
متن کاملA solution of nonlinear fractional random differential equation via random fixed point technique
In this paper, we investigate a new type of random $F$-contraction and obtain a common random fixed point theorem for a pair of self stochastic mappings in a separable Banach space. The existence of a unique solution for nonlinear fractional random differential equation is proved under suitable conditions.
متن کاملA review on neutron shielding performance of nano-composite materials
Neutron sources employed in different applications in both medicine and industry. Due to the harmful effects of neutron particles on living organisms, radiation shields have played a vital role in radiation protection against neutrons. In recent decade, numerous investigations conducted on the design and fabrication of nanocomposites as more efficient shielding materials against fast and therma...
متن کاملNeutron Scattering Technique
Neutron scattering technique is the most modern method of sampling the dynamics and structural properties of molecular systems. Neutrons interact with atoms via nuclear which has nuclear forces that are very short ranged. For this reason, neutrons can better penetrate into sample matter and obtain the information that would have been able to by other methods, such as x-rays. In this paper, we s...
