摘要：
A quantum analog to the classical Poincare surface of section, based on the Husimi function, is calculated for the quartic oscillator: H = 1/2(P(x)2 + P(y)2) + x2y2/2 + alpha(x4 + y4). The corresponding quantum densities in phase space are analyzed, and they show certain localization properties for a large number of states. (C) 1994 John Wiley & Sons, Inc.
