Alpha Cluster Condensation in ¹²C and ¹⁶O — •G. Röpke¹, A. Tohsaki², H. Horiuchi³, and P. Schuck⁴ — ¹FB Physik, Universität Rostock, D-18051 Rostock, Germany — ²Department of Fine Materials Engineering, Shinshu University, Ueda 386-8567, Japan — ³Department of Physics, Kyoto University, Kyoto 606-8502, Japan — ⁴Institut de Physique Nucleaire, F-91406 Orsay Cedex, France

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.
