Supermultiplet structure and decay properties of hypernuclear 1/sup +/ resonances in /sub Lambda //sup 6/Li

The excitation function for the 0h/2 pi omega and 1h/2 pi omega levels of /sub Lambda //sup 6/Li, populated in the (K/sup -/, pi /sup -/) reaction at theta /sub pi /=0 degrees , is calculated in the framework of the translationally invariant shell model. One-baryon and cluster widths for the decay of resonance hypernuclear states are estimated. The decay properties of those state are shown to be essentially given by the Young tableaux selection rules. Very good agreement with recent experimental data at p/sub K/=790 MeV/c at CERN is achieved. The decay of /sub Lambda //sup 6/Li* into excited /sub Lambda //sup 4/He*(/sub Lambda //sup 4/H*) with subsequent hypernuclear gamma -emission is discussed as well. (13 refs).
