相对论和非相对论理论模型研究奇异核的性质

Investigation of Properties of Exotic Nuclei in Relativistic and Norelativistic Models

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 8}P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 8}P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...
