For both fundamental reasons and potential applications, the process of K-excitation by heavy ions at intermediate velocity has been re-investigated experimentally and theoretically and the main results are described here. The nature and the origin o

A variational procedure is developed for obtaining the geometry of a scattering medium between a source and a detector. This medium maximizes the radiative flux through the detector. It is shown that the variational formalism leads to an equation who
