Proton halo of ${}^8$B in a microscopic model

Abstract

The experimentally predicted existence of a proton halo in ${}^8$B is confirmed by dynamical microscopic multiconfiguration cluster model calculations. The thickness of the proton halo in ${}^8$B is 0.5 $fm$ while in ${}^8$Li a 0.4 $fm$ thick neutron halo has been found. It is shown that the huge quadrupole moment of ${}^8$B partly comes from the very distortable ${}^7$Be core.
