摘要
本文对200A GeV”^(32)S 与核乳胶相互作用产生的各种靶核碎片进行鉴别.采用δ电子积分计数法基本能分辨质子与α粒子.用此分辨方法,测出黑粒子中质子能谱.从谱型说明黑粒子主要是从激发靶核蒸发出来的.
Each target fragments from 200 A GeV ^(32)5 interacting with nuclear emul- sion is discriminated.The proton and α-particle can be distionguished by using δ-electron integral count method.The proton energypectrum from black particles is measured and it is indicated that the black particles is mainly come from the evaporation of excited target.
