Elastic electron scattering with CH2Br2 and CCI2Br2:The role of the polarization effects
文献摘要：
We present elastic electron scattering cross sections with holmethane molecules CH2Br2 and CC12Br2 in the low-energy region ranging from 0.01 eV to 20 eV.The calculations are performed with the R-matrix method in static-exchange plus polarization(SEP)and close-coupling(CC)approximations.The integral,differential,and momentum transfer cross sections are calculated.The convergence of the obtained cross sections is checked at four different levels of SEP approxi-mation.The predicted positions of the resonances agree well with available results.The precise resonance parameters are found to be sensitive to the treatment of polarization effects employed.We find that the polarization has a substantial effect on the cross sections,and this effect becomes even more important for lower impact energies.
