High-order isospin-dependent surface tension contribution to the fourth-order symmetry energy of finite nuclei
High-order isospin-dependent surface tension contribution to the fourth-order symmetry energy of finite nuclei
The relation between the fourth-order symmetry energy ${E}_{\text{sym,4}}({\ensuremath{\rho}}_{0})$ of nuclear matter at saturation density ${\ensuremath{\rho}}_{0}$ and its counterpart ${a}_{\text{sym,4}}(A)$ of finite nuclei in a semiempirical nuclear mass formula is revisited by considering the high-order isospin-dependent surface tension contribution to the latter. We derive the full expression of ${a}_{\text{sym,4}}(A)$, which includes …
