Popis:	The validity of nucleon-molecular-orbital picture is discussed for the12C +13C system by using the orthogonalized coupled-reaction-channel rotating molecular-orbital (RMO) model. Specific RMO states, namely positive-parity ground RMO states, are well described by the picture of a covalent molecule, while the adiabaticity for RMO states is not satisfied in general because of the appearance of Landau-Zener radial couplings in the RMO basis. However, we show, by transforming the RMO basis to adiabatic basis, that the adiabatic molecular-orbital picture is again established.Momentum-dependent coupling interactions dominate transition phenomena in this diabatic basis, contrary to the assumption made in the classical Landau-Zener theory.
