    "abstract": "A curious effect is uncovered by calculating the it time evolving probability\nof reflection of a Gaussian wave packet from a rectangular potential barrier\nwhile it is perturbed by reducing its height. A time interval is found during\nwhich this probability of reflection is larger (``superarrivals\u0027\u0027) than in the\nunperturbed case. This nonclassical effect can be explained by requiring a wave\nfunction to act as a ``field\u0027\u0027 through which an action, induced by the\nperturbation of the boundary condition, propagates at a speed depending upon\nthe rate of reducing the barrier height.",
