Effective Nucleon Masses in Symmetric and Asymmetric Nuclear Matter

E. N. E. van Dalen, C. Fuchs, Amand Faessler

The momentum and isospin dependence of the in-medium nucleon mass are studied. Two definitions of the effective mass, i.e. the Dirac mass $m_D^{\ast }$ and the nonrelativistic mass $m^*_…
