WebThe most widely studied theory is that of Feshbach, Kerman, and Koonin (FKK) (1980), due to its relatively straightforward computational structure. This theory partitions the reaction process into two types of scattering: multistep compound (important at the lowest incident energies), and multistep direct (important at higher incident energies).
