The asymptotic normalization coefficient (ANC) of9 C = 8 B+p deduced from 8 Li(d, p)9 Li reaction is used to obtainthe root-mean-square (rms) radius of the loosely bound proton in the 9C ground state. We obtain 1/2 = 3.61 fmfor the valence proton, which is significantly larger than the matter radius of 9 C. The probability of the valence proton outside the matter radius of 9 C is greater than 60%. The present work supports the conclusion that 9 Chas a proton halo structure.
