Fluctuations of macrovariables in nonlinear systems: Langevin equation approach
(Kluwer Academic Publishers-Plenum Publishers; Plenum Publishing Corporation ; Springer Science+Business Media, 1977-01)
Fluctuations in nonlinear Markovian systems are studied by the Langevin equation method using system-size expansion. Langevin equations with different random sources are constructed for the description of fluctuations to ...
Deconvolution of neutron depth profiling spectra
(Elsevier, 1986-09)
Iterative methods for determining deconvolued depth profiles from measured neutron depth profiling (NDP) energy spectra are presented. The methods account for energy broadening caused by system noise, energy straggling, ...
Single-scatter Monte Carlo compared to condensed history results for low energy electrons
(Elsevier, 1992-10)
A Monte Carlo code has been developed to simulate individual electron interactions. The code has been instrumental in determining the range of validity for the widely used condensed history method. This task was accomplished ...
Monte Carlo analysis of the backscattering of radiation from a sphere to a plane
(Elsevier, 1990-02)
A Monte Carlo method is described for computing the backscattering of radiation from a sphere situated above an emitting plane. Numerical results are given and compared with analytic bounds for this problem which were ...
Impact of variations in physical parameters on glow curves for planchet heating of TL dosimeters
(Elsevier, 1994-12-30)
This study consists of a theoretical analysis of the directional planchet heating of Thermoluminescent Dosimeters (TLD) with an emphasis on influence of radiation field type, TL material properties, and heating scheme ...
Quantum Statistics and Slow Neutron Scattering by Gases
(The American Institute of Physics, 1967-12-15)
A surprisingly simple expression in ``closed form'' for the cross section d2σ/dΩdϵ for the scattering of thermal neutrons (including polarized neutrons) from an ideal quantum gas is derived. This result extends the work ...
Vibrational spectra, assignments and normal coordinate analyses for crystalline zirconium tetrachloride and tetrabromide
(Elsevier, 1981)
Raman and far-IR spectra have been obtained of crystalline ZrCl4 and ZrBr4. The observed frequencies have been interpreted on the basis of the C2h symmetry of the Bravais unit cell and have been subjected to a normal ...
