One-dimensional α condensation of α-linear-chain states

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