Alpha-cluster Condensations in Nuclei and Experimental Approaches for their Studies
Abstract
The binding energies of nuclei in their ground states as a function of mass number show a peculiar systematic behavior, explained by the liquid drop model. Deviations from a smooth curve are due to shell effects, and are some times discussed to be related to the formation of α-clusters. The specific properties of the nucleon-nucleon force, namely the saturation which occurs if the spin and isospin quantum numbers are both coupled to zero, produces a very strong binding of α-particles [1]. In addition, due to the internal structure of the αs an increased (30%) central density is observed compared to the the usual central density in nuclei. The α-particle is therefore a unique cluster subsystem in nuclei.
