Reflating the nucleus: The pachydermous droplet model

NUCLEAR STRUCTURE A=10-260; calculated rms radii as function of mass number using leptodermous droplet model (LDM) and pachydermous droplet model (PDM); deduced that the tendency of the standard droplet model (DM) to lead to excessive squeezing of nuclei can be rectified by going beyond the leptodermous picture and attributing to the DM a surface skin of finite thickness.

ATOMIC MASSES N=8-240; calculated masses for 6884 nuclei using new family of three Hartree-Fock-Bogoliubov (HFB) mass models HFB-30, HFB-31, and HFB-32, and respective interactions, BSk30, BSk31, and BSk32, respectively. New feature of a purely phenomenological pairing term that depends on the density gradient. Best fit to the database of 2353 experimental nuclear masses from AME-2012, and to rms charge-radius data.
