吸引势阱的波包散射

Wave packet scattering from an attractive well

G. Kälbermann

摘要:

在二维空间中数值研究了波包在吸引势阱中的散射。结果证实了以前发现的一维情况。大角度散射波是一个多峰相干训练波。大角度散射对于低撞击速度和所有碰撞参量都是极其重要的。对于比阱更长的包,该效应消失。实验来检测的polychotomous行为的建议。

英文摘要:

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.
