摘要：

Recently, ultranarrow resonances have been observed in the diamagnetic Rydberg spectrum of the lithium atom. We show that they originate from an accidental destructive interference, which, in turn, is due to the chaotic character of the classical behavior. Our numerical simulations show that their statistical properties axe well described by a random-matrix model.
