摘要：

The results on non-spreading Michelangelo wave packets [7,8] Are generalized to the case of a semi-open two-level system when some fraction of atoms falls back to the lower state due to spontaneous transitions. The proposed approach is based on the solution, of the Generalized Optical Bloch Equations for the atomic density matrix. The spatial features of arising non-spreading wave packets as well as the atomic momentum distribution are compared with the case of an open two-level system.
