| 摘 要： | 采用相对论和非相对论理论模型可描述奇异核的性质 .相对论平均场理论预言了2 6,2 7,2 8P存在一个质子晕 ,而27,28,29S存在两个质子晕 .最近 ,MSU的最新的实验发现了2 6,2 7,2 8P核存在一个质子晕.采用相对论 Hartree- Fock理论研究了 Fock项和矢量介子对奇异核性质的贡献,研究表明交换项和矢量介子对非常丰中子核性质的影响非常不同于对稳定线附近核性质的影响.同时,采用形变的Hartree- Fock- Bogoliubov理论研究了某些轻核同位素链的性质和形变.

| Abstract: | Properties of exotic nuclei were described by relativistic and norelativistic models. The relativistic mean field theory predicts one proton halo in 26, 27, 28 P and two proton halos in 27, 28, 29 S. One proton halo in 26, 27, 28 P has been found recently in MSU lab. The relativistic Hartree Fock theory was used to investigate contribution of Fock term and isovector mesons to the properties of exotuc nuclei. It turned out that the influence of the Fock term and isovector... |
