ABSTRACT
Single-particle behavior of the nucleon motion is present even in highly collective phenomena like fission or fusion. Neither phenomenological liquid drop models nor microscopic shell models could account for all nuclear properties. Any variant of the liquid drop model fails to explain ground-state deformation and fission-fragment mass asymmetry. By subtracting LDM masses from the experimentally determined ones (see Figure 4, Chapter 2), the extra binding of the nuclei possessing a magic number of nucleons is very clearly seen.
