摘 要: | The asymptotic normalization coefficient (ANC) of^9C=^8B p deduced from S Li(d, p)^9 Li reaction is used to obtain the root-mean-square (rms) radius of the loosely bound proton in the ^9C ground state. We obtain (r^2)1/2 = 3.61 fm 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.
