TL;DR: For light hypernuclei, core-excited states were resolved for the first time as mentioned in this paper, and the peak structure reflecting the Lambda shell structure was observed for light and heavy HetNets.

TL;DR: In this article, an experiment demonstrating the production of double-Lambda hypernuclei in (K(-),K(+)) reactions on (9)Be was carried out at the D6 line in the BNL alternating gradient synchrotron.
Journal ArticleDOI

TL;DR: In this paper, a clear peak was observed in the {sup 4 He(K{sup {minus},{pi}{sup +}) spectrum at 600 MeV/c and 4.4{plus_minus}0.4
Journal ArticleDOI

TL;DR: In this article, a search for {sigma} hypernuclear states in p -shell hypernuclei has been performed with the Moby Dick spectrometer and the low energy separated beam (LESB-2) at the Brookhaven Alternating Gradient Synchrotron (BNL AGS), and no narrow states have been observed for targets of {sup 6}Li and {sup 9}Be in (K{sup -}, {pi}{sup {+-}}) reactions, either for bound state or continuum regions.
Journal ArticleDOI

TL;DR: Two smaller peaks were clearly observed at excitation energies of 2.6 and 6.9 MeV and are interpreted as states where the [sup 11][ital C] excited core and a [Lambda] hyperon in the [ital s] orbit are weakly coupled.
