One-Dimensional Alpha Condensation Of Alpha-Linear-Chain States In C-12 And O-16

We present a new picture that the alpha-linear-chain structure for C-12 and O-16 has one-dimensional a condensate character. The wave functions of linear-chain states that are described by superposing a large number of Brink wave functions have extremely large overlaps of nearly 100% with single Tohsaki-Horiuchi-Schuck-Ropke wave functions, which were proposed to describe the alpha condensed "gaslike" states. Although this new picture is different from the conventional idea of the spatial localization of alpha clusters, the density distributions are shown to have localized alpha clusters due to the inter-alpha Pauli repulsion.
