In the present work one- and two-channel approaches using the expansion of the effective-range function K(E) in powers of energy E are applied to obtain the asymptotic normalization coefficients(ANCs) and vertex constants (VCs) for the d+Alpha system. The coefficients of the K(E) expansion are found by fitting the d phase shifts. By analytic continuation of K(E) thus obtained to the corresponding poles the ANCs and VCs for D wave d Alpha scattering resonances with total angular momentum J^pi = 1^+, 2^+, 3^+ are calculated for the first time. The 1^+ resonance and the bound state of ^6Li (J = 1^+) are considered jointly in the two-channel (S+D) effective-range approach and the ANCs and VCs for the ground ^6Li state are found.
