Vibrationally inelastic cross-sections of the water molecule by
low-energy electron collisions are computed by solving the
rigorous vibrational coupled channel (VCC) equations within a
body-fixed (BF) formulation. The results have been obtained down
to very low energies above the threshold openings for the three
normal modes of the target. A comparison with existing
experiments, and with the most recent calculations, clearly shows
the good agreement with measurements achieved by our present
results, especially at collision energies of less than 1
never analysed in previous work.
