| Abstract: | Gas-like α cluster states are investigated in 16O with the use of 4α OCM (orthogonality condition model) and GEM (Gauss expansion method). α-particle condensed state is found slightly above the 4α threshold as the ${0_6^+}$ state. The candidates of the ${alpha + {^{12}{rm C}(0_2^+)}}$ rotational states are also found at a few megaelectron volt above the condensate. The ${0_6^+}$ state is shown to have an analogue structure to the Hoyle state ${({^{12}{rm C}}(0_2^+))}$ and its relation with the α+ Hoyle-like rotational states is also discussed. |
