Properties of A=7-9 Drip-Line Nuclei in RMF Theory

The relativistic mean-field (RMF) theory is used to calculate the properties of A = 7-9 drip-line nuclei (7)Li, (7;9)Be, (8;9)B, and (9)C. sytematic 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 (8)B is reproduced well, and the two-proton halo in (9)C is predicted. The calculations show that the RMF theory is valid in studying the properties of light drip-line nuclei.
