摘要：

Low density states near the 3 alpha and 4 alpha breakup threshold in C-12 and O-16, respectively, are discussed in terms of the alpha-particle condensation. Calculations are performed in OCM (Orthogonality Condition Model) and THSR (Tohsaki-Horiuchi-Schuck-Ropke) approaches. The 0(2)(+) state in C-12 and the 0(6)(+), state in O-16 are shown to have dilute density structures and give strong enhancement of the occupation of the S-state c.o.m. orbital of the alpha-particles. The possibility of the existence of alpha-particle condensed states in heavier n alpha nuclei is also discussed.
