Abstrakt: The spatial structure of the lowest 0 , 0 , 2 and 2 states of the C nucleus is studied within the 3 model with the Buck, Friedrich and Wheatley potential with Pauli forbidden states in the and waves. The Pauli forbidden states in the three-body system are treated by the exact orthogonalization method. The largest contributions to the ground and excited 2 bound states energies come from the partial waves and . In contrast to the bound states, for the Hoyle resonance 0 and its analog state 2 , dominant contributions come from the and configurations, respectively. The estimated probability density functions for the C(0 ) ground and 2 excited bound states show mostly a triangular structure, where the particles move at a distance of about 2.5 fm from each other. However, the spatial structure of the Hoyle resonance and its analog state have a strongly different structure, like . In the Hoyle state the last particle moves far from the doublet at the distance between fm and fm. In the Hoyle analog 2 state the two alpha particles move at a distance of about 15 fm, but the last particle can move far from the doublet at the distanse up to fm. [ABSTRACT FROM AUTHOR]
