Description
The halo phenomenon is a hot topic in the nuclear structure study from both the theoretical and experimental points of view. Deep insights into the nucleon-nucleon interaction are needed to understand this phenomenon. Many neutron or proton-halo nuclei are observed in neutron or proton-rich nuclei by the experiments. With the strangeness quark included, the hyperon could influence the halo phenomenon, providing new insights into the baryon-baryon interaction. In this talk, we will investigate the hyperon halo orbits in light and heavy neutron-rich hypernucleus [1, 2]. We will also explore the possibility of a hyperon halo with a multi-hyperon hypernucleus. The lack of experiment data for the hyperon-hyperon interaction provides a chance to discuss the influence of the ambiguity of the hyperon-hyperon interaction on the multi-hyperon halo.
