摘要：

Asymptotic normalization coefficients (ANCs) of the 0(1)(+),0(2)(+),1(1)(-),2(1)(+),3(1)(-)(l(ith)(pi)) bound states of (16)Oare deduced from the phase shift data of elastic alpha-C-12 scattering at low energies. S matrices of elastic alpha-C-12 scattering are constructed within cluster effective field theory (EFT), in which both bound and resonant states of O-16 are considered. Parameters in the S matrices are fitted to the precise phase shift data below thep-(15)Nbreakup energy for the partial waves of l=0,1,2,3,4,5,6, and the ANCs are calculated by using the wavefunction normalization factors of O-16 propagators for l=0,1,2,3. We review the values of ANCs, which are compared with other results in the literature, and discuss uncertainties of the ANCs obtained from the elastic alpha-C-12 scattering data in cluster EFT.
