Information Content and Sensitivity of Matrix Elements to Structural Changes in Complex Scattering System

Abstract

Physics Department researchers at the University of Arizona investigated a number of basic problems that are central to understanding light scattered from complex systems. They started with simple geometrical systems-- spherical and cylindrical geometries with known optical constants that are directly amenable to theory. Theorists can calculate exactly every scattering property (the matrix elements) of these systems and experimentalists can measure them with arbitrarily high accuracy and precision. Yet some of the most basic questions about: (a) the information content in the various matrix elements, (b) their response to large and small changes in particle property, (c) their specificity to a particular parameter change, (d) the information density per scattering angle interval, and (e) ways to quantify changes, still needed careful study. The research was an optical study of fundamentals systems theorectically solvable and experimentally obtainable. The things learned from this study and described in this report will give insight to the matrix element data obtained from complex scattering systems.
