Neutron Interactions with Matter

چکیده
How neutrons interact with matter aflkcts the ways in which assays can be pdormed with neutrqs. Neutron interactions with the assay material affkct the interpretation of neutron measurements and limit the amount of fissile material the assay instrument can contain safely. A neutron detector is based on some neutron interaction with the material in the detector. Also, neutron interactions with shielding materials are necessary to protect radiation workeri. This chapter provides iimdamenial information about neutron interactions that are important to nuclear material measurements; The that section describes the interactions on the microscopic level where individ@ neutrons, interact with other particles and nuclei. The concepts are then extended to macroscopic interactions with bulk compound materials. !,

Neutron dose-equivalent buildup factors were calculated for point isotropic neutron sources irradiating infinite slablike shields of lead, iron and water using the MCNP code. The factors are presented for some source neutron energies in the range from 0.025 eV to 14 MeV, and for shield thicknesses from 0.5 to 10 mfp. Since the MCNP code considers all kinds of neutron interactions with matter, a...
متن کاملThe study of neutron interactions with soft tissue using Monte Carlo simulation using the source PF
The most important part of neutron therapy treatment (NCT1) is to achieve a beam of neutrons with suitable energy and intensity, as well as the least pollution and damage. In this study, in order to correct the neutron spectrum from D-D fusion and its use in neutron therapy, a set of different materials which are called the Beam Shaping Assembly (BSA) was placed in the direction of energy 2.45 ...
متن کاملInvestigation of Developed Shield Composition to Neutron Shielding in Treatment Room for BNCT to Reduce Clinical Effects
Background and Aim: One of the best radiotherapy methods that have been suggested for the treatment of cancers such as brain, head and neck, skin, and recently liver is boron neutron capture therapy. Therefore, neutron shielding in the treatment room is important because the absorption of neutrons in the shield may lead to the production of gamma rays, which can have destructive effects. While ...
متن کاملMany-body Theory of Nuclear and Neutron Star Matter
We present results obtained for nuclei, nuclear and neutron star matter, and neutron star structure obtained with the recent Argonne v18 twonucleon and Urbana IX three-nucleon interactions including relativistic boost corrections. These interactions predict that matter will undergo a transition to a spin layered phase with neutral pion condensation. We also consider the possibility of a transit...
متن کاملHypernuclear Physics for Neutron Stars
The role of hypernuclear physics for the physics of neutron stars is delineated. Hypernuclear potentials in dense matter control the hyperon composition of dense neutron star matter. The three-body interactions of nucleons and hyperons determine the stiffness of the neutron star equation of state and thereby the maximum neutron star mass. Two-body hyperon-nucleon and hyperon-hyperon interaction...
