The elastic α - 12 C scattering at low energies for l = 0 , 1 , 2 , 3 , 4 , 5 , 6 is studied in eﬀective ﬁeld theory. We discuss the construction of the S matrices of elastic α - 12 C scattering in terms of the amplitudes of sub-threshold bound and resonant states of 16 O, which are calculated from the eﬀective Lagrangian. The parameters appearing in the S matrices are ﬁtted to the phase shift data below the p - 15 N breakup threshold energy, and we ﬁnd that the phase shifts are well described…
