Equation of state of cold nuclear matter extracted from nuclear masses by the droplet model

The information of the equation of state of cold nuclear matter is extracted from the experimental nuclear masses by the droplet model. The result shows the asymmetry dependence of the equation of state in a more direct way than has been done before. It shows that the spherical or the deformed nuclear region appears alternately as the bulk nucleon density of the core of nuclei increases. An explanation of why the rms fit of the droplet model to the nuclear masses gives a very broad minimum region of the nuclear compressibility is possible based on this work
