Abstract We have used spectroscopic factors extracted from the (d,p) transfer reactions to calculate asymptotic normalization coefficients and root-mean-square (rms) radii for the valence neutron in 14,15C. The obtained rms radii are 4.57±0.30, 5.78±0.36 and 5.82±0.60 fm for the first 1-, 0- excited states of 14C and the ground state of 15C, which are 1.84, 2.33 and 2.32 times larger than the size of their cores, repectively. These large values imply that 15C as well as 14C in its first 1-, 0- states are halo nuclei.
