In this chapter, devoted to microscopic approaches, we derive the general expression of the decay width, known as the Fermi golden rule, by using the time-dependent Schrödinger equation. We also introduce the equivalent surface formula containing the preformation amplitude. Then, we show that these relations can be recovered within the reaction Feshbach theory and R-matrix approach. We describe the Resonating Group Method, as the most general microscopic approach to analyze the emission of composite objects.
