Hyperon Haloes in A Hypernuclei in the Relativistic Continuum Hartree—Bogoliubov Theory

We investigate the existence of a single-Α hyperon halo in 3Α^15C and a two-Α hyperon halo in 4Α^16C.Ground-state properties of hyperon carbon isotopes,such as density distributions,single particle levels in the canonical basis,the binding energy,Α separation energy and radii,are calcuated and discussed by using the relativistic continuum Hartree-Bogoliubov theory.The hyperon halo phenomenon in 3Α^15C and 4Α^16C is supported by the discussion of the weakly bound state 1p3/2,extended density distribution and small separation energy of the Α hyperon.
