Pre-equilibrium processes are important in nuclear reactions at intermediate energies. 

This seminar presents pre-equilibrium reactions in the broader context of nuclear reaction mechanisms for nucleon- and light-ion–induced reactions.

The main physical picture and the key modelling approaches are briefly reviewed. The focus is on the core ideas behind the different pre-equilibrium models used today.

Their effects on experimental observables are discussed, including excitation functions, energy spectra, and angular distributions of emitted particles. Indirect effects on observables linked to gamma emission and fission are also addressed.

Finally, a few recent studies on neutron-induced reactions are presented.
