标题： Spontaneous decay of resonant energy levels for molecules with moving nuclei

摘要： 我们考虑具有动力核的Pauli-Fierz哈密顿量，并在假设初始时没有自由光子的情况下研究共振电子能级之间的跃迁。 将小精细结构常数和重核的极限相结合，使我们能够在主导阶证明Born-Oppenheimer近似的有效性，并提供一个简单的自发衰变率公式。 显示英文摘要

摘要： We consider the Pauli-Fierz Hamiltonian with dynamical nuclei and investigate the transitions between the resonant electronic energy levels under the assumption that there are no free photons in the beginning. Coupling the limits of small fine structure constant and of heavy nuclei allows us to prove the validity of the Born-Oppenheimer approximation at leading order and to provide a simple formula for the rate of spontaneous decay.
