Abstract
The experimental asymptotic normalization coefficient determined from peripheral transfer reactions is used to obtain the root-mean-square radius of the wave function for the loosely bound proton in It is shown that the asymptotic region contributes most and that matching of the interior wave function with the asymptotic part yields a nearly model-independent radius. We obtain for the root-mean-square (rms) radius of the last proton, much larger than the rms radius of the core. This large value and the fact that the asymptotic part of the proton wave function contributes to the rms radius are good sign that is a halo nucleus.
