    "abstract": "We consider the time evolution of the occupation probabilities for the 2s-2p\ntransition in a hydrogen atom interacting with an external field, V(t). A\ntwo-state model and a dipole approximation are used. In the case of degenerate\nenergy levels an analytical solution of the time-dependent Shroedinger equation\nfor the probability amplitudes exists. The form of the solution allows one to\nchoose the ratio of the field amplitude to its frequency that leads to temporal\ntrapping of electrons in specific states. The analytic solution is valid when\nthe separation of the energy levels is small compared to the energy of the\ninteracting radiation.",
