Abstract
Conversion processes for (7)(Xi) H are discussed as a typical example of the double-Lambda hypernuclear formation via a neutron-rich Xi stat e. (5)(lambda lambda) H is formed with a surpisingly large branching r atio of about 90% from H-7(Xi) that is produced by the K-, K+) reactio n on the Li-7 target. The (7)(Xi) H state has a narrow width, 0.75 MeV , and its population can be confirmed by tagging K+ momentum.
