在相对论连续谱Hartree-Bogoliubov理论中，采用NLSH有效相互作用，研究了N = 3同位素和镜像核的基态性质.配对相关性由密度依赖的δ力来考虑。计算结果表明，8B和9 C的质子密度分布有长尾，9 C的核密度有增加的趋势，成对的价态质子使晕分布收缩。用Glauber模型计算了8B（9 C）+12 C反应的截面，与实验数据符合较好.我们认为8B是一个单质子晕核，9 C是一个双质子晕核。
The ground-state properties of N = 3 isotones and mirror nuclei have been investigated in the Rrelativistic Continuum Hartree-Bogoliubov theory with the NLSH effective interaction. Pairing correlations are taken into account by a density-dependent δ-force. The calculations show that the proton density distributions of 8B and 9C have a long tail, the core has an increasing tendency of 9C and the paired off valence protons make the halo distribution shrink. The cross sections for the 8B(9C)+12C reaction which are consistent with the experimental data are calculated using the Glauber model. On the whole, we think that 8B is a one-proton halo nucleus and 9C is a two-proton halo nucleus.
