INTERFERENCE EFFECTS BETWEEN ELECTRON-EXCHANGE AND THE SPIN-ORBIT INTERACTION

In accordance with predictions made in 1974, recent measurements demon strated that the elastic e-Cs scattering is richer in physics than a s imple addition of Mott scattering and nonrelativistic exchange would p rovide. Now it is time to take a closer look at the general analysis o f Burke and Mitchell and think about further experiments that will sti mulate improvements in calculations and lead to a deeper understanding of the underlying physics.
