摘要：
We present results of numerical experiments performed on quantum two-spin systems, which permit a direct comparison of quantum and classical invariant structures. Two complementary representations are discussed: Husimi distributions, i. e., the decomposition of stationary states in terms of coherent states, and a second type of distribution which gives a measure of localization of coherent states during time evolution.
