    "abstract": "A one-dimensional scattering problem off a $\\delta$-shaped potential is\nsolved analytically and the time development of a wave packet is derived from\nthe time-dependent Schr\\\"odinger equation. The exact and explicit expression of\nthe scattered wave packet supplies us with interesting information about the\n\"time delay\" by potential scattering in the asymptotic region. It is\ndemonstrated that a wave packet scattered by a spin-flipping potential can give\nus quite a different value for the delay times from that obtained without\nspin-degrees of freedom.",
