Abstract
Much of our present understanding of atomic and molecular structure comes from collision experiments. This type of experiment was started by Rutherford in 1910 with high speed alpha particles as the bombarding projectiles. Since then other particles with various speeds have been used for bombardment. The fundamental experimental set-up, in which a single beam is used to bombard the target, is basically the same as in the past sixty years. The beauty of such an arrangement is probably its simplicity. The shortcoming is the unobserved phase which contains half of the collision information. In this talk, a new type of collision experiment is suggested. We show that the unobserved information can be recovered. In the proposed experiment, the single incident beam is replaced by two coherent beams, and the rest of the experimental set up remains the same. The well known coherent beams are photon and electron beams. With these beams, we can perform the experimental study, which In turn will double the present experimental information on the structure of atoms and molecules.
