Droplet mass formula fit

A mass fit of the droplet model is presented ¹). To gain more confidence in the values of the thirteen coefficients used, we fitted in addition the best-known isobar parabolae. By this procedure the position and the width of the β-valley are fitted and the symmetry J and the surface stiffness Q proved to be the only relevant parameters. Finally the binding energy at the bottom of the β-valley is refitted by altering the other parameters. The thus obtained nuclear masses are compared with experimental data as well as with the TCH model presented earlier.
