Zh. Liu et al., Asymptotic normalization coefficients and neutron halo of the excited states in B-12 and C-13 - art. no. 034312, PHYS REV C, 6403(3), 2001, pp. 4312
The transfer reactions of B-11(d,p) B-12 and C-12(d, p) C-13, at incident e
nergy of 11.8 MeV, have been used to extract asymptotic normalization coeff
icients and root-mean-square radii for the last neutron in B-12 and C-13. I
t is found experimentally that the second (J(pi) = 2-) and third (J(pi) = 1
(-)) excited states in B-12 and the first (J(pi) = 1/2(+)) excited state in
C-13 are the neutron halo states, whereas the third (J(pi) = 5/2(+)) excit
ed state in C-13 is a neutron skin state.
