Abstract

Equivalent sharp radii of a number of nuclei are calculated with the droplet model, using parameters that have been determined by the Hartree-Fock (HF) method with a given force (Gogny). They are found to be systematically smaller than the sharp radii given by direct HF calculations on the nucleus in question with the same force. This is shown to be a result of nuclear matter being squeezed by the surface tension much more in the droplet model than in the HF method. Inclusion of higher-order terms in the droplet model's expansion in powers of A13 in no way helps to remove the anomaly, and in fact serious questions concerning the convergence of this expansion arise.
