Double-{Lambda} hypernuclear formation via a neutron-rich {Xi} state
- Institute for Nuclear Study, University of Tokyo, Tanashi, Tokyo 188 (Japan)
Conversion processes for {sub {Xi}}{sup 7}H are discussed as a typical example of the double-{Lambda} hypernuclear formation via a neutron-rich {Xi} state. {sub {Lambda}{Lambda}}{sup 5}H is formed with a surprisingly large branching ratio of about 90{percent} from {sub {Xi}}{sup 7}H that is produced by the ({ital K}{sup {minus}},{ital K}{sup +}) reaction on the {sup 7}Li target. The {sub {Xi}}{sup 7}H state has a narrow width, 0.75 MeV, and its population can be confirmed by tagging {ital K}{sup +} momentum. {copyright} {ital 1996 The American Physical Society.}
