论文摘要
我们通过Hartree-fock模型研究了C和B同位素的高核，它们具有Skyrme型核子核子和核子 - 杂种相互作用。计算出的$λ$绑定能与可用的实验数据一致。我们在光C和B同位素中的HyperON $ 1p $ state中发现了HALO结构，其扩展波函数超出了核表面。我们还发现增强的电偶极转换在$ 1p $ - 至$ 1s $ -HYPERON州之间，这可能是这种超声晕结构的证据。
We study the hypernuclei of C and B isotopes by Hartree-Fock model with Skyrme-type nucleon-nucleon and nucleon-hyperon interactions. The calculated $Λ$ binding energies agree well with the available experiment data. We found halo structure in the hyperon $1p$-state with extended wave function beyond nuclear surface in the light C and B isotopes. We also found the enhanced electric dipole transition between $1p$- and $1s$-hyperon states, which could be the evidence for this hyperon halo structure.
