    "abstract": "The tunneling of Gaussian wave packets has been investigated by numerically\nsolving the one-dimensional Schr\\\"odinger equation. The shape of wave packets\ninteracting with a square barrier has been monitored for various values of the\nbarrier width, height and initial width of the wave packet. Compared to the\ncase of free propagation, the maximum of a tunneled wave packet exhibits a\nshift, which can be interpreted as an enhanced velocity during tunneling.",
