HYPERNUCLEAR PHYSICS AT TJNAF

The strangeness electroproduction experiments, just starting to take d ata at TJNAF, are very promising for giving very useful information to understand the nuclear and nucleonic structure and reaction mechanism . The experimental program on hypernuclei already approved concerns fe w body, light nuclei and heavy nuclei. It will be possible to investig ate these hypernuclear systems for the first time by photo-and electro - induced reactions, allowing to obtain very useful information such a s Lambda-N interaction and weak interaction in the nuclear medium in a complementary way with respect to what can be done with hadron probes .
