Gas-Like Cluster States in Finite Nuclei
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 α+12C(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 (12C(0+2)) and its relation with the α+ Hoyle-like rotational states is also discussed.
