Study of the contributions of chemical and van der Waal forces to interaction between fluorine and Ar, Kr and Xe, using molecular beam scattering investigations of integral scattering cross sections
Abstract
Molecular beam scattering experiments were developed to investigate the interaction between F-atoms and noble gas atoms. The phenomena occurring during elastic scattering in the thermal energy domain are explained by the example F-Xe. A comparison with experiments described in the literature led to a measurement method to determine the velocity dependence of integral scattering cross sections of the systems F-Ar, F-Kr, and F-Xe in the energy domain between 3 and 160 meV, with high accuracy. The measurements show well resolved oscillation structures. The measurements were evaluated with model calculations using the elastic approximation and the Hund'she coupling case C, and compared with other spectroscopic investigations and potential calculations. The van der Waals and chemical binding character of the different molecular state is determined.
