  Wave packet scattering off an attractive well is investigated in two spatial
dimensions numerically. The results confirm what was found previously for the
one dimensional case. The wave scattered at large angles is a polychotomous
(multiple peak) coherent train. Large angle scattering is extremely important
for low impinging velocities and at all impact parameters. The effect
disappears for packets more extended than the well. Experiments to detect the
polychotomous behavior are suggested.
