Sažetak
The spatial dispersion of the single-nucleon wave functions is analyzed using the self-consistent mean- field framework based on nuclear energy density functionals and with the harmonic-oscillator approximation for the nuclear potential. It is shown that the dispersion depends on the radial quantum number n but displays only a very weak dependence on the orbital angular momentum. An analytic expression is derived for the localization parameter that explicitly takes into account the radial quantum number of occupied single-nucleon states. The conditions for single-nucleon localization and formation of cluster structures are fulfilled in relatively light nuclei with A≤30 and n=1 states occupied. Heavier nuclei exhibit the quantum liquid phase of nucleonic matter because occupied levels that originate from n>1 spherical states are largely delocalized. Nevertheless, individual α-like clusters can be formed from valence nucleons filling single- particle levels originating from n=1 spherical mean- field states.
