英文摘要 | We establish a relation between the equation of state of nuclear matter and the fourth-order symmetry energy a(sym, 4)(A) of finite nuclei in a semi-empirical nuclear mass formula by self-consistently considering the bulk, surface and Coulomb contributions to the nuclear mass. Such a relation allows us to extract information on nuclear matter fourth-order symmetry energy E-sym,E- 4(rho(0)) at normal nuclear density rho(0) from analyzing nuclear mass data. Based on the recent precise extraction of a(sym, 4)(A) via the double difference of the "experimental" symmetry energy extracted from nuclear masses, for the first time, we estimate a value of E-sym,E- 4(rho(0)) = 20.0 +/- 4.6 MeV. Such a value of E-sym,E- 4(rho(0)) is significantly larger than the predictions from mean-field models and thus suggests the importance of considering the effects of beyond the mean-field approximation in nuclear matter calculations.
