Description

A new method to evaluate the curvature correction term to the surface tension coefficient based on the nuclear equation of state, is suggested. Among the advantages of the introduced approach one can mention the minimal set of assumptions used and the possibility to link the bulk and surface properties of the nuclear matter. In the present work it is shown that the “gedanken” experiment with the infinite nuclear matter and a chosen volume $V$ in it can give the possibility to evaluate the Tolman $\delta$ -correction for any EOS of the form $\Delta{P}=P-P_0=f\left(\frac{V_0-V}{V_0}\right)$ describing the system evolution along the coexistence curve. It is also obtained the temperature dependence of the curvature correction term in the surface tension. It can be seen that with increasing temperature the role of the curvature correction term increases. That might be important when analyzing the results of the high energy heavy ion collision experiments. E.g. in studying the properties of the hadronic matter in the vicinity of critical point and in calculating yields of light fragments. The obtained quantitative results for the correction term are in accord with the existing data and with the theoretical predictions regarding the interparticle distance.
