Sudden Approximation

Abstract Differential cross section measurements are reported for scattering of an improved He-atomic beam by crossed beams of Pyrrole, Furane and Thiophene. The damping of the DCS diffraction oscillations is used to extract reliable anisotropic intermolecular potentials, applying the infinite order sudden approximation (IOSA).

Linearly Polarized

The scattering of a positron by a muon in the presence of a linearly polarized laser field is investigated in the first Born approximation. The theoretical results reveal: (1) At large scattering angle, an amount of multiphoton processes take place in the course of scattering. The photon emission processes predominate the photon absorption ones. (2) Some nonlinear phenomena about oscillations, dark angular windows, and asymmetry can be observed in angular distributions. We analyze the cause giving rise to dark windows and geometric asymmetry initially noted in the potential scattering. (3) We also analyze the total differential cross-section, the result shows that the larger the incident energy is, the smaller the total differential cross-section is. The reasons of these new results are analyzed.

Direction Of Polarization

In this paper, we investigate the intensity dependence of a free–free transition in the presence of a bichromatic laser field. Based on the first Born approximation, we calculate the differential cross section and total differential cross section versus the field intensity. This dependence relates to the momentum of the incident electron, the ratio of the two frequencies, and the phase difference between the two components of the bichromatic laser field. While the two intensity components are comparable, this dependence is the most striking. The results also show that the intensity dependence relates to the geometrical configurations between the direction of polarization of the laser fields and the incident electron.
