研究了１４．６，６０和２００ＡＧｅＶ１６Ｏ离子诱发核反应中靶核碎片的角分布及其关联，得到靶碎片的角分布有能量无关性，并且在方位角方向的分布表现为各向同性，靶碎片的极角和方位角之间在目前的能量下关联现象不明显，灰粒子和黑粒子之间存在着正关联现象并在灰粒子较大时趋近于饱和．
The angular distribution and correlation of the target nuclear fragments in 14.6, 60 and 200AGeV16O ion-induced nuclear reactions were studied. The angular distribution of the target fragments was found to be energy-independent and the distribution in the azimuthal direction was isotropic. The correlation between the polar angle and azimuth under the current energy is not obvious. There is a positive correlation between the gray particles and the black particles and close to saturation when the gray particles are larger.
