The decay width is not very sensitive to the nuclear mean field parameters, because the preformation amplitude is a coherent superposition of many single-particle configurations, including states in continuum. The situation changes for transitions to excited states. In this chapter, we show that the decay width is very sensitive to the structure of the wave function in the daughter nucleus. We analyze the fine structure to 2+ vibrational states in the α-decay in terms of the Quasiparticle Random Phase Approximation. It is shown that this method is able to describe the main experimental features concerning both electromagnetic and α transitions.
