摘要: We construct a spherical domain wall which has baryon charge distributed on sphere of finite radius in Skyrme model with sixth-order derivative term and modified mass term. Its distribution energy density likewise takes the form sphere. In order to localize at we need negative coefficient front positive sixth stabilize soliton. Increasing pion pronounces shell-like structure configuration.
