Alpha Cluster in Hartree-Fock Calculations

Hartree-Fock (HF) calculations have been performed fcr ¹²C nucleus assuming a trigonal D_3h equilibrium configuration. Different aspects including symmetry, kinds of two-body interactions are investigated. The HF calculations have been carried out using a velocity dependent effective potential of s-wave interaction. The results are compared with previous calculations. In all HF calculations no deviation from axial symmetry is obtained.
