Topic:New Insights into Small-Angle Electron Scattering: Guiding Measurements and Theory

Speaker: Professor Alfred Z, Msezane (Clark Atlanta University)

Date & Time: Thursday, October 5, 2000 1:00 P.M.

Place: Room 140 VMC

The problem of measuring reliably small-angle electron differential cross-sections of atoms, ions and molecules are well documented in the literature. Through diversity, national and international collaborations as well as partnerships, research at the center for theatrical studies of physical systems have developed novel theatrical approaches to resolve several long-standing problems in theoretical atomic physics. In particular we discuss the Lassettre Limit Theorem and attendant normalization of measured relative electron differential cross sections. Through an appropriate representation, the limit of generalized oscillator strength at zero momentum transfer is reached when starting from any electron impact energy and without traversing the nonphysical region. The forty-year old problem is thus resolved.
