Abstract

Abstract A new approach to the determination of atomic matrix elements is described. In this method, measurement of spectral features of two-photon light scattering processes allows for extraction of matrix elements in terms of a fiducial quantity. In particular, the spectral location of zeros in the Rayleigh or Raman scattering cross-section permits one to make a mapping of the matrix elements into the frequency domain, where they may be reliably determined. This method is also applicable to excited-state transitions. Illustrations are made for Rayleigh scattering off the ground state in atomic Li and Cs.
