The nucleonic localization function has been used for a decade to study the formation of alpha-particles in nuclei, by providing measure having nucleons given spin single place. However, differences interpretation remain, compared density nucleus. In order better understand respective role and densities alpha-particle cluster states or alpha-decay mechanism, both an analytic approximation microscopic calculations, using energy functionals, are undertaken. is shown anti-centrifugal effect, not sensitive level compactness itself. It probes purity spatial overlap four possible (spin, isospin) states. provides, addition, information on cluster. roles also analyzed case emission. More generally, criteria assess prediction alpha-cluster nuclear provided.
