Alpha Cluster Condensation in 12C and 16O — •G. Röpke1, A. Tohsaki2, H. Horiuchi3, and P.

A new α-cluster wave function is proposed which is of the α-particle condensate type. Applications to 12C and 16O show that states of low density close to the 3 and 4 α-particle thresholds in both nuclei are possibly of this kind. It is conjectured that all self-conjugate 4n nuclei may show similar features.
