Description

We have carried out an experiment to search for a neutron-rich hypernucleus, 6ΛH, by the 6Li(π−,K+) reaction at pπ−=1.2 GeV/c. The obtained missing-mass spectrum with an estimated energy resolution of 3.2 MeV (FWHM) showed no peak structure corresponding to the 6ΛH hypernucleus neither below nor above the 4ΛH+2n particle decay threshold. An upper limit of the production cross section for the bound 6ΛH hypernucleus was estimated to be 1.2 nb/sr at 90% confidence level
