Theoretical Study of Ca(4s5p1P) Yields Ca(4s5p3P) Transitions in Collision with Noble Gases: Integral Cross Sections and Alignment Effects. (Reannouncement with New Availability Information).

摘要

The interpretation of the dependence of the cross section on initial polarization will be guided by diatomic spectroscopy and a consideration of the crossings between these potential curves. A new simple statistical model, based on the consideration of the reflection symmetry of the initially prepared state, will provide the point of departure for the prediction of the polarization dependence. The exact quantum cross sections agree well both with the predictions of the statistical model and with the recent experimental results from Leone's laboratory at JILA. In addition the calculated cross sections increase with decreasing collision energy, since the crucial crossing point is reached by the attractive branch of the potential.
