A possibility of α-cluster structure in nuclei around ^<20>Ne is examined in terms of a model based on the assumption of weak coupling between an α cluster an ^<16>O core. The model treats dynamically the coupling of α-^<16>O relative motion with a particle (p)- and a hole (h)motion in an average nuclear field of ^<16>O. The K^π= rotational band of ^<20>Ne (α+^<16>O) is plausibly explained with an effective α-^<16>O potential having repulsive core and state-dependent attractive well. The low-lying anomalous-parity levels of ^<19>F (α+^<16>O+h) and the ground rotational band of ^<21>Ne (α+^<16>O+p)are reasonably understood in terms of an effective nucleon-α potential with the essential features of the potential in free space. The hole and particle are treated in the weak- and strong-coupling schemes, respectively. The K^π=2^- rotational band of ^<20>Ne^* (α+^<16>O+p+h) is well interpreted in the strong-coupling scheme for the p-h pair. In conclusion, certain successes of the model seem to suggest an importance of α-like four-body correlation or molecular aspect in light nuclei.
