Abstract：
The experimental data of the ¹³C(d,p) ¹⁴C reaction are used to extract the asymptotic normalization coefficients of the overlap integral, the root-mean-square radii 2>^1/2 and the probabilities D₁ outside the range of the interaction radius R^N for the last neutron of the 1^－ and 0^－ excited states in ¹⁴C. We obtain 2>^1/2=4.57±0.30fm, 5.78±0.36fm and D 1=55.7%, 63.9% for these two states, respectively. These large values are the good sign that the 1^－ and 0^－ excited states in ¹⁴C are neutron halo states.
