The electromagnetic monopole (E0) transition of the 12C nucleus, the 0+ground state to three α-particles (3α) continuum states, is calculated by applying the Faddeev three-body formalism in coordinate space accommodating the long range Coulomb potential between α particles. Results show that there are two 0+ states, 12C(03+) and 12C(04+) states at excitation energies around 10 MeV, which is consistent with results of recent semi-microscopic calculations and analysis of α-12C inelastic scattering.
