    "abstract": "We investigate entanglement between electronic and nuclear degrees of freedom\nfor a model nonadiabatic system. We find that entanglement (measured by the von\nNeumann entropy of the subsystem for the eigenstates) is large in a statistical\nsense when the system shows ``nonadiabatic chaos\u0027\u0027 behavior which was found in\nour previous work [Phys. Rev. E {\\bf 63}, 066221 (2001)]. We also discuss\nnon-statistical behavior of the eigenstates for the regular cases.",
