    "abstract": "Branch points in the complex plane are responsible for avoided level\ncrossings in closed and open quantum systems. They create not only an exchange\nof the wave functions but also a mixing of the states of a quantum system at\nhigh level density. The influence of branch points in the complex plane on the\nlow-lying states of the system is small.",
