摘要：

We revisit our multiple-scattering method to treat low-energy elastic electron collisions with (H(2)O)(2). Calculations are performed for different geometries of the water dimer with different dipole moments. The effect of the dipole moment of the cluster is analysed. The elastic cross sections are compared to R-matrix results. Good agreement is found above 1 eV for all geometries. The results confirm the validity of the technique.
