Abstract The asymptotic normalization coefficient (ANC) of 9C = 8B+p deduced from 8Li(d,p)9Li reaction is used to obtain the root-mean-square (rms) radius of the loosely bound proton in the 9C ground state. We obtain (r2)1/2 = 3.61fm for the valence proton, which is significantly larger than the matter radius of 9C. The probability of the valence proton outside the matter radius of 9C is greater than 60%. The present work supports the conclusion that 9C has a proton halo structure.
