An analysis of the differential cross sections of the l2C (d ,p )13C (ground state, org.s., 1 /2J) and inBe(c/,/?)"Be (g.s., 1 /2, ) reactions at the incident deuteron energies of 11.8, 25.9, and 30 MeV for the first system, and 12.0 and 25.0 MeV for the second system has been performed by applying the coupled-reaction-channels method. The spectroscopic factors 5cxpI, asymptotic normalization coefficients (ANCs), and rms radii of the last neutron in the ground states and the first excited states of the stable l3C and the radioactive "B e nuclei were extracted. The existence of neutron halos in the first excited state of 13C and the ground state of "B e is confirmed. The rms radii of halos in these states were found to be 5.72 ± 0.16 and 8.0 ± 0.2 fm, respectively, in agreement with experimental results. We showed that a halo is also formed in the 0.32 MeV
Abstract.We have performed coupled reaction channels calculations of the (d,p) reactions on 12 C and 10 Be at laboratory energies of 12, 25, and 30 MeV leading to the ground and first excited states of 13 C and 11 Be. We found spectroscopic factors S exp , asymptotic normalization coefficients (ANCs) and root mean square radii of the last neutron in these states. Our calculations confirm the existence of neutron halos in the first excited state of 13 C, as well as in the ground and the first excited states of 11 Be. We found that the neutron transfer dominates at energies about 12 and 25 MeV and demonstrated that the states with enlarged radii are formed in the reactions of a peripheral type, which satisfy the criterion of a peripherality: C 2 =S exp b 2 =const, where C is the ANC and b is the single-particle ANC.
