| 英文摘要 | In this paper we study the volume and surface symmetry energy coefficients (c(sym)((V)) and c(sym)((S))) by using the double differences of "experimental" symmetry energies. We assume a(sym) = c(sym)((V)) - c(sym)((S))/A(1/3) and obtain c(sym)((V))= 31.26 +/- 0.32 MeVand c(sym)((S)) = 52.15 +/- 1.12 MeV, or c(sym)((V)) = 32.10 +/- 0.31 MeV and c(sym)((S)) = 58.91 +/- 1.08 MeV, depending on the form of theWigner energy. The uncertainties of these coefficients are smaller than those in the literature. The values of c(sym)((V)) and k(S/V) are unstable for differentmass regions if one assumes a(sym) = c(sym)((V))/(1 + k(S/V)/A(1/3)). We notice an odd-even staggering in the double differences of "experimental" symmetry energies under a few situations, and suggest that the pairing interaction might not be properly taken into account in the current mass formulas. |
