Screened Coulomb scattering versus Thomson scattering
European Journal of Physics, 2002The authors reexamine the basics of classical scattering of a particle from the early models of a neutral atom governed by the Thomson potential, a screened Coulomb potential, and a screened Yukawa potential.

Scattering and Inverse Scattering
1993For a given potential, the scattering method has been commonly used to find the wave functions in quantum mechanics. An inverse process of this scattering is to find the potential from known scattering data. Such a process is called the inverse scattering method. If the potential satisfies a nonlinear evolution equation (the differential equation u t =

We all know that blue skies and red sunsets are due to the “Rayleigh scattering” of sunlight. But beyond that, Rayleigh scattering means different things to different scientists.

Interferometric Scattering Microscopy
Annual Review of Physical Chemistry, 2019Interferometric scattering microscopy (iSCAT) is an extremely sensitive imaging method based on the efficient detection of light scattered by nanoscopic objects. The ability to, at least in principle, maintain high imaging contrast independent of the exposure time or the scattering cross section of the object allows for unique applications in single ...

Multiple scattering and scattering cross sections
The Journal of the Acoustical Society of America, 2018The scattering cross section for a cluster of scatterers can be calculated using various methods, either exactly or by invoking various approximations. Of special interest are methods in which the scattering properties of individual members of the cluster are used. The underlying question is: Can the contribution to the cluster's cross section from any

Scatter Simulation Including Double Scatter
IEEE Nuclear Science Symposium Conference Record, 2005, 2006We propose and evaluate a new scatter simulation algorithm to correct for scattered events in 3D PET. The algorithm simulates both single and double scatter. We show that single and double scatter distribution can have different shapes. This may cause difficulties if the total scatter is estimated by scaling the single scatter contribution.

Scattering Matrices in Many-Body Scattering
Communications in Mathematical Physics, 1999Let \(\{X_a; a\in I\}\) be a family of linear subspaces of \(\mathbb{R}^n= X_0\), \(X_1= \{0\}\), and \(X^a\) the orthocomplement of \(X_a\). The author treats \(S\)-matrices of the many-body Hamiltonian \(H= \Delta+\sum_{a\in I}(\pi^a)^* V_a\). Consider \(h_a= \Delta+ \sum_{b\leq a}V_b\) on \(\mathbb{L}^2(X^a)\). Let \(\varepsilon_\alpha\), \(\alpha= (
