500 AMeV ⁵⁶Fe诱发乳胶核反应弹核碎裂研究

摘要: 通过利用日本放射线医学综合研究所( NIRS ) 重离子医用加速器( HIMAC) 产生的束流照射国产的核-4型原子核乳胶，对500 AMeV ⁵⁶Fe诱发乳胶核反应粒子产生进行了研究。讨论了500 AMeV ⁵⁶Fe诱发乳胶核反应弹核碎片的多重数分布，并与其他结果进行了比较。结果表明，弹核碎片平均多重数随靶核质量的增加而增加，与入射能量无关。A stack of domestic N-4 nuclear emulsion was exposed to 56Fe ions at 500 AMeV at the HIMAC of NIRS. Particle production was investigated in 56Fe-Em interactions. The multiplicity distribution of projectile fragments was given in this paper and compared with other experimental results of heavy ion induced nuclear reactions in nuclear emulsion. The results show that the multiplicity of projectile fragments increase with the increasing target mass, and there
is no dependence on the projectile energy.
