Abstract: (arXiv)
Within Bombaci's phenomenological single-nucleon potential model we study the neutron-proton effective mass splitting mnmpm_n^*- m_p^* in neutron-rich matter. It is shown that an effective mass splitting of m_n^*<m_p^* leads to a symmetry potential that is inconsistent with the energy dependence of the Lane potential constrained by the nucleon-nucleus scattering experimental data.
