Abstract | Neutron hole states in the 1s shell have been studied in the n(K/sup - /, pi /sup -/) Lambda strangeness-exchange reaction on /sup 6/Li, /sup 7/Li, /sup 9/Be, and /sup 12/C targets at the CERN Proton Synchrotron. The excitation energy and the width of the states as well as the differential cross section have been determined. The clear similarity with the 1s proton hole states observed in (p,2p) reactions indicates that the presence of the Lambda -particle can be taken into account within the weak-coupling model. In this way the (K/sup -/, pi /sup -/) reaction can be used for the study of Lambda -states as well as for the investigation of neutron hole states produced at very low momentum transfer. (22 refs). |
