Cluster-Model Theory of the Ground-State Rotational Band ofNe20

The excitation energies of the ground-state rotational band as well as the reduced transition rate for the transition from the first excited state to the ground state in ${\mathrm{Ne}}^{20}$ have been calculated with the use of cluster wave functions. The agreement between the calculated and observed values suggests that the properties of the ground-state rotational band in ${\mathrm{Ne}}^{20}$ can also be explained in terms of cluster motion.
