Abstract
This work aims to use an important method Galitskii-Migdal-Feynman (GMF) for diatomic molecules 132Xe2, to calculate the effective phase shifts which are then used to compute the effective total and viscosity cross sections at low density and temperature . this study has shown that it’s crucial to include partial waves up to ; for , the effect of the potential becomes negligible .
Comparing with partial waves cross sections we deduce that the cross section is dominated by S-wave scattering for low energy (wave number k < 0.1 Å-1), otherwise D and G partial waves dominate . The highest peak rises from the partial effective D and G-wave resonance, where the system sustains a quasi-bound state trapped by the centrifugal barrier. The average cross section is also determined.
