研究了 69MeV/u36 Ar轰击Be靶的碎裂产物与Si靶反应引起的前角区轻带电粒子的发射产额与原子核同位旋、原子核序数的关系 .发现前角区轻带电粒子发射产额对于丰质子核的结构非常敏感 ,与同位旋存在一种指数关系 .因此可以把前角区轻带电粒子发射产额作为探测丰质子核结构的一种手段 ,也是一种新的验证一个核是否具有质子晕结构的实验证据 .
The relationship between the emission yield of light-charged particles in the anterior horn region caused by 69 MeV / u36 Ar bombardment Be target fragmentation products and the Si target reaction, the isospin and atomic number of the nucleus was investigated. It was found that the yield of light- The structure of abundance protons is very sensitive and has an exponential relationship with the isosphere, so the yield of light-charged particles in the anterior horn can be used as a means to detect the abundance of proton nuclei and a new method to verify whether a nucleus has Experimental evidence of proton halo structure.
