✦ Synopsis

An idea for producing AA hypernuclei, based on the expectation of efficient formation of Ah fragments at (K-,K+) reaction points, was proposed in Refs. [1,2]. A Z particle produced predominantly in the quasi-free region is absorbed into the target nucleus through a rescattering process with a nucleon and the Z-p + AA conversion in the nucleus leads to a AA-sticking intermediate state (AA compound nucleus), followed by fragmentation into AA products. Now, a new experiment (E906) to detect AA hypernuclei by observing characteristic 7~~ mesonic decays at (K-,K+) reaction points is in progress at BNL-AGS. In fact, the major results of the present calculations were reflected in the proposal for this experiment.
