CAS号:

性质:(一)direct reaction  入射粒子接近靶核时,不经过形成复合核阶段,而直接引起的核反应,包括削裂反应、拾取反应、敲出反应及电荷交换反应等。(二)impulsive reaction  又称脉冲反应。分子反应产物的角分布有强烈的方向性(向前或向后散射),过渡态的寿命(反应时间)比其转动周期(约1ps)还短的反应称直接反应。这种反应的机理可分为两种类型(如图1):(1)剥离机理(剥裂反应,stripping reaction);(2)回弹机理。剥离机理:如反应K+I2+KI+I,碘原子有较大的电子亲合势,K夺取了一个I沿入射方向向前飞去,散射角很小,另一个I像个旁观者,其线动量在反应前后几乎不变,故又称旁观者-抢夺模型。回弹机理(rebound mechanism):如K+ICH3=KI+CH3,由于K与ICH3撞击参数很小,两粒子很接近,强烈的近程排斥作用迫使KI与CH3回弹,相背向飞散开,故表现为向后散射。
