Abstract
A scenario is given.for the formation of XI- states and the transition s to states with double-LAMBDA in anticipation of observations, especi ally in the KEK-E224 experiment. First, the production cross sections of XI- hypernuclear states by (K-, K+) reactions are calculated within the framework of the distorted-wave impulse approximation. Next, the transition rates from XI- hypernuclear states to possible double-LAMBD A states are obtained, which are closely related to single- and double -LAMBDA emissions after the XI-p-->LAMBDALAMBDA conversion in nuclei.
