It is shown that the Landau-Zener transition mechanism due to the formation of molecular orbitals of the active neutron exists in the inelastic scattering ${}_{}{}^{13}{}_{}{}^{}\mathrm{C}$${(}^{12}$C, ${}_{}{}^{12}{}_{}{}^{}\mathrm{C}$${)}^{13}$${\mathrm{C}}^{\mathrm{*}}$ (3.086 MeV, ${\mathrm{}(1/2)\mathrm{}}^{+}$). The evidence stems from characteristic changes of the angular distributions observed as a function of the incident energy.
