Description

Nuclear systems show two kinds of natures, i.e., cluster and mean field aspects, providing rich phenomena in nuclei. The cluster aspect is found in ground state correlations, which induce nuclear deformations and polygon shapes such as the triangle of $^{12}$C and tetrahedron of $^{16}$O. In the excited states, it contributes to low-lying monopole and dipole excitations. Proton and alpha scattering reactions are useful in clarifying the properties of those cluster states. Particular attention is paid on the monopole transitions via inelastic scattering. The monopole mode in $^{8}$He is also discussed.
