Isospin dependence of the nuclear surface tension - art. no. 034318

Using the Thomas-Fermi nuclear model we have constructed a standard dimensi onless function (a simple hyperbola) which can be used to estimate the depe ndence of the surface tension gamma on the relative neutron excess delta fo r a variety of models, using only the models' properties calculated for sta ndard (semi-infinite) nuclear matter with delta =0. We add some comments cl arifying the relation between the Gibbs and the droplet model definitions, gamma (mu) and gamma (e), of the surface tension.
