摘要：

The coupled reaction channels model calculations of the direct Be-8 transfer in the alpha+C-12 elastic and inelastic (to the 7.65 MeV 0(2)(+) and the 9.65 MeV 3(1)(-) states) scattering have been performed. It is shown that the cluster configuration with zero relative angular momentum dominates in 0(2)(+) state being 4.4 times larger than that in the ground state. In the 3(1)(-) state, a dominance of the p-orbital motion is found. The condensed properties are confirmed in the Hoyle state. The 3 alpha exotic, but hardly a condensed structure of the 3(1)(-) state is found.
