摘要
本文对1.2AGeVAr+BaI2和2.1AGeVNe+NaF碰撞的Bevalac流光室4π实验事件末态粒子的横向运动特征进行了研究。发现末态粒子的横向运动不仅存在方位角关联,而且还存在横向动量模的关联。研究表明;在Ar十BaI2碰撞实验中,粒子的横向动量模关联比Ne+NaF碰撞实验强。并且,两种碰撞实验中的粒子方位角关联比其各自的横向动量模关联强。
Using 4π data for 1. 2 A GeV Ar+BaI2, and 2. 1 AGeV Ne+NaF collisions at the Bevalacstreamer chamber,the charactor of transverse motion of final particles is studied. It is foundthat not only the azimuthal correlations but also the transverse momentum magnitude correlations exist in the transverse motion of final particles. Our studies indicate that the transverse momentum magnitude correlations for collisions of Ar+BaI2 are stronger than that forcollisions of Ne+NaF. Moreover,the azimuthal correlations are stronger than transverse momentum magnitude correlations for two collision experiments.
