a) Optimal density profile of neutrons n_n and protons n_p for spherical nuclear droplets at average baryon density n_b = 0.0475 fm^-3. The associated baryon and proton numbers, proton fraction x_p = Z/A in percentage, and radius of the cell are shown. The vertical dashed line marks the location of the end of the WS cell. b) The same for n_b = 0.065 fm^-3. c) The same for n_b = 0.076 fm^-3.
