An effect of a wave-packet scattering off an attractive one-dimensional well is found numerically and analytically. For a wave packet narrower than the width of the well, the scattering proceeds through a quasibound state of almost zero energy. The wave reflected from the well is a polychotomous (multiple-peak) monochromatic and coherent train. The transmitted wave is a spreading smooth wave packet. The effect is strong for low average speeds of the packet, and it disappears for wide packets.
