【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。更多还原

【Abstract】 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 drip-line nucleus,and can be used to check the current nuclear model under extreme condition.Experimental observation of ground-state two-proton decay has been widely considered as a challenge because of very low production cross section.In this short paper,the breakthrough of searching ground-state two-proton decay is briefly reviewed,which was made more than 40 years after the early theoretical prediction was proposed.更多还原
