Abstract

Direct reactions proceed in a single step, allowing to disentangle structural properties of nuclei from the reaction mechanism. The availability of radioactive beams gives rise to a renewed activity in this field enlarging the opportunities to explore the single-particle properties of exotic nuclei. Different kinds of direct reactions have been employed in different energy regimes. At high energies, the removal of one(two)-nucleon(s) (referred to as nucleon knockout in this text) from a fast exotic projectile has been extensively investigated, exploring the nuclear structure of the peripheral tail of wave functions and providing a direct insight into the single-particle properties. More than 25 years of experimental and theoretical work will be reviewed in this lecture. This exploration has recently been rejuvenated with the possibility of quasi-free scattering applied to rare isotopes. This method will be a substantial part of the program of future experimental facilities, with the results of pilot experiments now coming to light. Quasi-free scattering will complement the information gained with nucleon knockout studies, exploring deeper regions in the wave function and allowing the determination of spectral functions for both weakly and deeply bound nucleons. This lecture provides a general overview of the experimental achievements reached so far using both complementary techniques. A brief introduction to the reaction mechanisms and a simplified interpretation of the observables obtained will be presented.
