[en] This summary is not intended to give an extensive review of all what has been said during the three days about technics, experiments and theories. It will be rather a brief and simple overview of what I felt during the meeting while listening to the different talks, discussions and participating to the round tables which were also a very important part of the workshop and contributed a lot to its success. This summary will be organized as follows: in a first part I shall briefly describe the basic problems that one is faced with ''exclusive'' measurements. Finally, we shall briefly review some of the theoretical problems existing at intermediate bombarding energies since any experiment would initially rely heavily on theoretical considerations
