吸引势阱中的相干多分裂波
Coherent polychotomous waves from an attractive well
摘要：
通过数值计算和解析计算，发现了一维势阱中波包散射的一种新效应.对于比阱宽窄的波包，散射通过能量几乎为零的准束缚态进行。从井中反射的波是多波（多峰）单色且相干的训练。所发射的波是扩展的平滑波包。对于低平均速率的数据包，这种影响很强，而对于宽数据包，这种影响消失。
英文摘要：
A novel 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 quasi-bound 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.
