摘要: 介绍了质子晕研究在理论和实验方面的最新进展 ,着重讨论了 2 s1 d壳的晕核结构和不同理论模型预示2 6～28P和2 7～ 2 9S中质子晕的存在 ,最近的实验证实了 2 6～ 2 8P核存在一个质子晕.最后简要讨论了质子晕形成的条件. The new progress of proton halo researches in theory and experiment was introduced. Especially the structure of halo nuclei having 2s1d shell and the different models predicting the existence of proton halos in 26～28 P, 27～29 S were discussed. A recent experiment proving the existence of one proton halo in 26～28 P was reviewed and finally the conditions forming proton halo were discussed briefly.
