摘　　要：对中高能核-核碰撞碎裂过程进行研究,可以揭示核反应生成的α射弹碎片的产生机制.本文对400AMeV^(12)C诱发乳胶核反应产生的α射弹碎片与靶核碎片关联进行了研究,通过对已有实验数据的比较分析,得出α射弹碎片的产生,与靶核的半径大小有关,还和射弹和靶核碰撞时的中心相对横向距离有关.说明α射弹碎片多重数越大,作用事例的旁观体越大,射弹与靶核反应体越小,靶核的激发程度越弱,产生的靶核碎片的多重数也越小.The helium projectile fragments correlation of target nuclei fragments in^(12)C induced nuclear emulsion reactions at 400AMeV is studied.By analyzing the existing experimental data,it is found that,the production of the helium projectile fragments is not only related to the collision parameter b but also to the radius size of the projectiles and the target nucleus.It also shows that,with the increase of multiplicity of the helium projectile fragments,the larger the bystander of the case,the smaller the reactan of projectile and target nucleus,the weaker the excitation degree of the target nucleus,and the smaller the multiple number of the target nuclear fragments.
