説明

Electron-impact rotational excitations of HF and HBr are studied theoretically. Vibrationally elastic cross sections are calculated for the electron-molecule systems. The calculation is based on fixednuclei approximation with model potentials. The electrostatic potential is calculated using reliable ab initio molecular wave functions, and the effects of electron exchange and target polarization are taken into account approximately by means of free-electron gass models. The rotational transitions is obtained for j=0 →0,1,2(j is the rotational quantum number). The electron energies are 6-50 eV for HF and are 5-50 eV for HBr, respectively. The results of the rotational differential cross sections are compared with experimental data in 6,10 eV.
