Abstract [en]

The global mass dependence of the nuclear symmetry energy a(sym)(A) and its two basic ingredients due to the mean-level spacing epsilon(A) and effective strength of the isovector mean-potential K(A) is studied within the Skyrme-Hartree-Fock model. In particular, our study determines the ratio of the surface-to-volume contributions to a(sym)(A) to be r(S/V) similar to 1.6 and reveals that after removing momentum-dependent effects by rescaling epsilon and kappa with isoscalar and isovector effective masses, respectively, one obtains epsilon(star) approximate to kappa(star).
