The coherent structures of two phonons have been proposed as the sub-structure α+ of four-particle clusters for the light nuclei. In the same way the sub-structure β+ of four-hole clusters can also be given. Based on this the sub-structures between particle clusters and hole clusters in 16O and 18O have been chosen as examples for our investigation. It is found that there is a very strong repulsive force between them. Therefore the loose structure between particle cluster and hole cluster is of the lowest energy state. In this way, the deformations of these states have been explained from the microscopic structures. Moreover, these strucrures can coherently strengthen the E2 transition. Further in order to study the particle correlation in the medium nuclei, the L-S coupling coherent structure is extended to the pseudo L-S coupling coherent structure and the expressions are given in the j-j coupling representation. Some preliminary analyses are made for the nuclei around 56Ni by using these structures.
