摘要：
The energy-level spectrum of the protactinium atom (Pa, Z = 91) is simulated with a configuration interaction calculation. Levels belonging to the separate manifolds of a given total angular momentum and parity J(pi) exhibit distinct properties of many-body quantum chaos. Moreover, an extremely strong enhancement of small perturbations takes place. As an example, effective three-electron interaction is investigated and found to play a significant role in the system. Chaotic properties of the eigenstates allow one to develop a statistical theory and predict probabilities of different processes in chaotic systems.
