Basis Vectors

We discuss a method called quasi-sparse eigenvector diagonalization which finds the most important basis vectors of the low energy eigenstates of a quantum Hamiltonian. It can operate using any basis, either orthogonal or non-orthogonal, and any sparse Hamiltonian, either Hermitian, non-Hermitian, finite-dimensional, or infinite-dimensional. The method is part of a new computational approach which combines both diagonalization and Monte Carlo techniques.

In this paper, KTA-304 boron steel for low-energy neutron absorption and attenuation is studied by Monte Carlo method, and compared with the traditional SUS304 stainless steel. Taking into account some factors, such as processing conditions, corrosion resistance, hot ductility, etc. we may reasonably come to the conclusion that 1.13% boron concentration in the steel has a better absorption capacity to the low-energy neutron and can effectively reduce the secondary γ-ray effect, meeting the request of radiation protection with reduced material thickness. Besides, low-energy neutron attenuation coefficient was calculated at different boron concentrations of the steel in different energies, providing a reasonable basis for selecting the neutron shielding materials. The γ-rays released in the neutron capture process were considered, too.

The neutron flux and energy distribution of the neutrons produced in a gas cell were measured using a silicon semiconductor detector. The energy spectra produced by the borbardment of the silicon detector with neutrons were simulated using Monte Carlo techniques and were compared with the measured spectra
