【摘要】 用CR-39作为探测器和靶,研究了960AMeV²³⁸U离子和轻核(¹H、^120C、16O的相互作用.测定了²³⁸U离子在CR-39中的射程;²³⁸U与轻核相互作用的电荷变化平均自由程（mfp）和截面,并与理论计算值进行了比较;²³⁸U和轻核相互作用的平均多重数v=2.03,证明相互作用的主要形式是二裂变;反应产物的径迹按直径分布形成两个峰,测定了每个峰的径迹密度与两个峰总径迹密度之比.更多还原

【Abstract】 A CR-39 track detector was used both as a target and a detector to study the interaction of 960 A Mev ²³⁸U ions with light nuclei (¹H, ¹²C, ¹⁶O). The range mean free path and cross section of 960 A MeV ²³³U ions in CR-39 have been found to be 6.8 cm, 4.33 cm and 2160 mb respectively. The average multiplicity due to fragmentation of ²³⁶U projectiles with light nuclei has been found to be 2.03. It is shown that the most common mode of interaction is binary fission. The reaction products consist of two track peaks according to track diameter distribution. The ratio of track density of each peak to track density of reaction products comes out to be 20% and 80% respectively.更多还原
