摘要：

The correlation between the known theoretical calculated surface energies and the 'free' mobile electron density parameter, r(m), is studied. It is shown that the experimental data, both for simple and transition metals, are better fitted by the function r(m)(-4) than by r(m)(-3), which follows from the Miedema model of cohesion.
