Influence of bulk properties on the surface structure of finite nuclei

A self-consistent study of the structure of the nuclear surface is done using the semi-infinite nuclear matter approximation. It is found that surface thickness strongly depends on the nuclear matter saturation density. It is also shown that the extended Thomas-Fermi calculations fail to reproduce this important feature. Its implication on the effective surface compressibility coefficient Ks, and on the extraction of the nuclear matter compressibility coefficient K∞ from the measured finite nuclei values KA, are also illustrated
