We have carried out an experiment to search for a neutron-rich hypernucleus, , by the reaction at . The obtained missing-mass spectrum with an estimated energy resolution of 3.2 MeV (FWHM) showed no peak structure corresponding to the hypernucleus neither below nor above the particle decay threshold. An upper limit of the production cross section for the bound hypernucleus was estimated to be at 90% confidence level.
