Conclusions

The ''Journees d'etudes energies intermediaires'' at Grenoble have been devoted to the response function of hadronic systems. Following a discussion of ''QCD inspired'' models of the free nucleon, there have been presented theoretical predictions and ample experimental evidence for polarization effects of bound nucleons in the nuclear environment. The nuclear response has been studied with different probes. Experiments with kaons are particularly interesting, because they allow to implant strangeness into the nucleus. It is evident that there is a big challenge for new accelerator projects which could help to put more flavour into nuclei. There are plans to investigate strange nuclei by the reactions (γ,K±) and (e,e'K±) at the CEBAF laboratory, which will go into operation in 1992. Typical counting rates of 1 or 10 events per hour are expected for tagged photons and electoexcitation, respectively
