Abstract
We have carried out an experiment to search for a neutron-rich hypernucleus, by the 6(Lambda)H by the 6Li(pi(-), K+) reaction at p(pi)- = 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 6(Lambda)H hypernucleus neither below nor above the 4(Lambda)H+2n particle decay threshold. An upper limit of th production cross section for the bound 6(Lambda)H hypernucleus was estimated to be 1.2 nb/sr at 90% confidence level. (c) 2014 The Authors. Published by Elsevier B.V.
