Abstract

The transfer reactions of ${}^{11}\mathrm{B}{(d,p)}^{12}\mathrm{B}$ and ${}^{12}\mathrm{C}{(d,p)}^{13}\mathrm{C},$ at incident energy of $11.8 \mathrm{MeV},$ have been used to extract asymptotic normalization coefficients and root-mean-square radii for the last neutron in ${}^{12}\mathrm{B}$ and ${}^{13}\mathrm{C}.$ It is found experimentally that the second ${(J}^{\ensuremath{\pi}}{=2}^{\ensuremath{-}})$ and third ${(J}^{\ensuremath{\pi}}{=1}^{\ensuremath{-}})$ excited states in ${}^{12}\mathrm{B}$ and the first ${(J}^{\ensuremath{\pi}}{=1/2}^{+})$ excited state in ${}^{13}\mathrm{C}$ are the neutron halo states, whereas the third ${(J}^{\ensuremath{\pi}}{=5/2}^{+})$ excited state in ${}^{13}\mathrm{C}$ is a neutron skin state.
