Abstract

Tunnel-current spectroscopy used to determine the quantum-mechanical energy levels of an electron in a quantum well in a magnetic field indicates the presence of concentrations of probability amplitude (wavefunction scarring). The experimental observations confirm the theoretical calculations. The spectra of the quantized energy levels, for systems that show chaotic motion, are not uniform and have fluctuations that are related to unstable periodic orbits. The orbits resemble scars in the wavefunction of the system.
