Four-body structure of neutron-rich hypernucleus ${}_{\Lambda }^6$H

Abstract

The structure of heavy hyperhydrogen ${}_{\Lambda }^6$H is studied within the framework of a $tnn\Lambda$ four-body cluster model. Interactions among the constituent subunits are determined so as to reproduce reasonably well the observed low-energy properties of the $tn,t\Lambda$ and $tnn$ subsystems. As long as we reproduce the energy and width of ${}^5$H within the error bar, the ground state of ${}_{\Lambda }^6$H is obtained as a resonant state.
