Acoustical scattering by radially stratified scatterers

The Journal of the Acoustical Society of America, 2008
A recursive solution procedure is developed to analyze the acoustical scattering by multilayer concentric circular cylindrical scatterers. The procedure is based on multiple scattering in the single-scatterer methodology originally proposed by one of the authors. The solution for a scatterer having an arbitrary number of layers is solved by recursively

Simultaneous Neutron Scattering and Raman Scattering

Applied Spectroscopy, 2009
The capability to make simultaneous neutron and Raman scattering measurements at temperatures between 1.5 and 450 K has been developed. The samples to be investigated are attached to one end of a custom-made center-stick suitable for insertion into a 100 mm-bore cryostat.

Light Scattering

Current Protocols in Protein Science, 1998
AbstractLight scattering methods can provide information about the native molecular weight, oligomeric composition, and gross conformation of a protein in solution. These methods are particularly well suited for studying large oligomeric systems or glycoproteins and can be used to characterize much larger structures involving protein such as viruses ...

Multiple scattering and scattering cross sections

The Journal of the Acoustical Society of America, 2018
The 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

Scattering Matrices in Many-Body Scattering

Communications in Mathematical Physics, 1999
Let \(\{X_a; a\in I\}\) 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= (

Scattering and Inverse Scattering

1993
For 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 =
