    本实验同时研究了40Ar+209Bi反应中周边碰撞和中心碰撞两者产生的关联裂变碎片，以及其与α粒子的再关联．对裂交碎片质量分布和能量分布随热裂变核初始温度演化的系统分析，发现中心碰撞和周边碰撞所形成的热核存在着不同的裂变行为．

    Correlated fission fragments from the 40Ar+209Bi reaction and their further correlation with αparticles have been studied for peripheral and central collisions simultaneously. The existence of differentfission behavior of hot nuclei formed in central and peripheral collisions was found from the systematicanalysis of the mass and energy distributions of fission fragments as a function of the initial temperature ofhot fissioning nuclei.
