摘　　要：用伴随粒子飞行时间方法,在10°—140°范围内测量了14.2 MeV中子在Zr上的弹性散射微分截面。用蒙特卡洛方法对中子在样品中的通量衰减,多次散射及有限角分辨进行了修正;并将测量数据与光学模型理论计算及他人的结果作了比较。The differntial elastic scattering cross sections of Zr for 14. 2 MeV neutrons are measured by the associated particle time--of--flight method at angles from 10° to 140°. The corrections for neutron flux attenuation, multiple scattering and finite geometry are performed by using Mon- te-Carlo method. The experimental results are compared with the available lata from other work and teh theoretical calculation.
