We investigate nucleon mass splitting at finite isospin chemical potential in the frame of the two-flavour NambuJona-Lasinio model.It is analytically proven that in the phase with explicit isospin symmetry breaking,the proton mass decreases and the neutron mass increases linearly in the isospin chemical potential.
