Distortion of Neutron Collision Density due to Resonance Scattering and Absorption

Resonance Raman Scattering and Collision-Induced Redistribution Scattering in I2

Light Scattering and Absorption due to Bacterial Activity in Water

There is a growing class of elementary particle detectors ("Large Water Cerenkov Detectors") which have a body of water (thousands of tons) as a sensitive medium. Particles are detected when they interact with the water and produce Cerenkov light, so detection efficiency relies on the transparency of the water. These detectors are active typically for many years and so biological activity is on...

Collision statistics for random flights with anisotropic scattering and absorption.

For a broad class of random walks with anisotropic scattering kernels and absorption, we derive explicit formulas that allow expressing the moments of the collision number n(V) performed in a volume V as a function of the particle equilibrium distribution. Our results apply to arbitrary domains V and boundary conditions, and allow assessing the hitting statistics for systems where the typical d...

The use of selected neutron absorption resonance filters to suppress spurious events on hot neutron spectrometers

Resonant absorption can be used as a filter for high energy neutron spectroscopy. Here we report the transmission of eight thin foil filters: erbium, indium, iridium, dysprosium, hafnium, gadolinium, cadmium and samarium, measured using neutron time-of-flight techniques over a range of energies (1 meV to 10 eV). Measured transmission is converted into energy-dependent absorption cross-section w...
