Neutron transport correction and density calculation in the neutron-gamma density logging
Applied Radiation and Isotopes, 2019Formation density is one of the most important parameters in formation evaluation. The radioisotope chemical sources are widely used in conventional nuclear logging tools. Considering security and environmental risks, the pulsed neutron generators have successfully replaced the Am-Be source in neutron porosity logging tools.

Nanodosimetric measurements and calculations in a neutron therapy beam
Radiation Protection Dosimetry, 2007A comparison of calculated and measured values of the dose mean lineal energy (y(D)) for the former neutron therapy beam at Louvain-la-Neuve is reported. The measurements were made with wall-less tissue-equivalent proportional counters using the variance-covariance method and simulating spheres with diameters between 10 nm and 15 microm. The calculated

Fast-neutron Spectra and Dose-rate Calculations
Health Physics, 1961A method and its application for calculating fast-neutron spectra and dose rates about the Lid Tank Facility source plate, the Bulk Shielding Reactor, and the Aircraft Shield Test Reactor are described. The method may be applied to any reactor whose shield is composed largely of hydrogenous materials. Dose rates and spectra calculated by the method are

MICROSCOPIC CALCULATIONS IN NEUTRON MATTER
International Journal of Modern Physics E, 2005The properties of neutron matter are investigated in the framework of the extended Brueckner–Hartree–Fock approximation at zero temperature. Self-consistent calculations using different realistic interactions are reported for pure neutron matter. In this contribution, all the self-energies are calculated self-consistently.

A neutron three-beam calculation
Physics Letters A, 1978Abstract A first calculation for a particular neutron three-beam case, (111, 1 11), is presented using the dynamical theory of diffraction. By simultaneous reflection on the net planes (111) and ( 1 11) one gets a forward (0) beam and two diffracted ( G and H ) beams with different properties.

Measurements and calculations of neutron scattering in the actinide region
Physical Review C, 1986Neutron scattering differential cross sections were measured for $^{232}\mathrm{Th}$, $^{238}\mathrm{U}$, and $^{239}\mathrm{Pu}$ at 14.1 MeV. Optical model calculations were performed using the coupled-channel formalism for deformed nuclei as given by Tamura. Several microscopic and phenomenological optical model potentials were tested for these heavy

Calculation of neutron spectra produced in neutron generator target: Code testing
Applied Radiation and Isotopes, 2018DT-neutron spectra calculated using the SRIANG code was benchmarked against the results obtained by widely used Monte Carlo codes: PROFIL, SHORIN, TARGET, ENEA-JSI, MCUNED, DDT and NEUSDESC. The comparison of the spectra obtained by different codes confirmed the correctness of SRIANG calculations.
