THE RADIUS OF 8B FROM THE ASYMPTOTIC NORMALIZATION COEFFICIENTS EXTRACTED FROM THE NEUTRON TRANSFER 12C(8LI,7LI)13C REACTION

By using the values of ANC for 8B→7Be+p the rms radius of 8B for the valence proton in ground state (2+, 0) has been determined. It has been found to be 3.54±0.16 fm and the matter radius of 8B to be 2.60 fm. The probability of the valence proton outside the matter radius of 8B is greater than 65%, the asymptotic part of the wave function contributes about 86% to the rms radius of the valence proton. The present result concludes that 8B is a protonhalo structured nucleus.
