摘要
使用新的相对论平均场力参数ＴＷ１和ＭＬ－ＳＨ对Ａ超核的基态性质进行了研究，发现上述参数能得到Λ超核令人满意的理论结果，两套参数的结果差别不大，特别是Λ超核的结果不依赖于有效核子一核子相互作用力参数，在研究超核中考虑了对关联的影响，发现它导致了奇偶效应。
The ground state properties of hypernuclei are studied theoretically using the relativistic mean-field theory with TM1 and NL-SH force parameters. It is found that these new parameters can very satisfactorily reproduce the ground state properties of the above hypernuclei. The parameter sets TM1 and NL-SH give a very similar description on the hypernuclei. The properties of hypernuclei in baryon hyperon systems are insensitive to the force parameters of effective nucleon-nucleon interaction.The influence of the pairing force is taken into account in the study of hypemuclei and it is found that it leads to the even-odd effect
