A novel way of demonstrating and visualizing quantum manifestations of Hamiltonian chaos is presented. The method is based on the calculation of invariants in the form of time averages of dynamical variables in microscopic states. The observed quantum nonintegrability effects are unmistakable images of well-understood phenomena of classical Hamiltonian chaos.
