在相对论平均场近似下，在手征场理论的框架内研究了有限核的性质。结果表明，与传统观点不同，有限核的正规型解是存在的。作者得到了这些解，并用它们计算了具有两个可调参数的核体性质。平均场正规解与所观测到的核的距离并不太远。该理论同时还包含异常类型的配置，在某些情况下，这些配置可能看起来比正常类型的配置束缚得更强。然而，对于标量介子质量的常规值（约500兆电子伏），只有一种可能性是一个正常的配置。
The properties of finite nuclei are investigated in the framework of a chiral field theory using relativistic mean-field approximation. It is shown that, in contrast with the conventional point of view, the normal-type solutions for finite nuclei do exist. The authors have obtained these solutions and used them to calculate the nuclear bulk properties with two adjustable parameters. The mean-field normal solutions are not so far from the observed nuclei. The theory simultaneously contains also configurations of abnormal type which in some cases may appear to be much more strongly bound than those of the normal type. However, for conventional values of the scalar meson mass m sigma ( approximately 500 MeV) only one possibility remains-that of a normal configuration.
