| Abstract: | The relativistic mean-field (RMF) theory is used to calculate the properties of A = 7-9 drip-line nuclei 7Li, 7,9Be, 8,9B, and 9C. Systematic deviations between experimental and theoretical binding energies are found. Possible reasons of these systematic deviations are discussed in terms of pairing energy. The root-mean-square (rms) radii of matter distributions for these nuclei agree with the experimental data quite well. The one-proton halo structure in 8B is reproduced well, and the two-proton halo in 9C is predicted. The calculations show that the RMF theory is valid in studying the properties of light drip-line nuclei. |
