原子核基态双质子衰变的研究进展
Recent Progress for Observation of Groundstate Twoproton Decay
-
摘要: 基态双质子衰变是质子滴线区原子核的一种奇异衰变。 它可以揭示质子滴线区原子核外层质子对的结构行为, 检验现有核模型理论应用于极端条件下原子核的正确性。 搜索基态双质子衰变是人们广泛关注的一个实验难题, 直到理论预言提出后40多年才取得明显进展。 简要介绍了这一研究的进展情况。 The ground-state two-proton decay is an exotic decay beyond proton drip line. It deals with the structure behavior of the proton pair at outside orbital in a proton dripline nucleus, and can be used to check the current nuclear model under extreme condition. Experimental observation of groundstate twoproton decay has been widely considered as a challenge because of very low production cross section. In this short paper, the breakthrough of searching groundstate twoproton decay is briefly reviewed, which was made more than 40 years after the early theoretical prediction was proposed.Abstract: The ground-state two-proton decay is an exotic decay beyond proton drip line.
