【摘要】 用伴随粒子飞行时间方法,在1.7°至25°范围内测量了14.2MeV中子在铅核上的弹性散射微分截面.用蒙特卡罗方法对中子在样品中的注量衰减,多次散射及有限角分辨做了修正.实验结果与其它测量及球形核光学模型作了比较.更多还原

【Abstract】 The differential elastic scattering cross sections of pb for 14.2MeV neutrons on pbnucleus are measured by the associated particle time-of-flight method at angles from 1.7. to 25.. The Corrections for neutron fluence attenuation, multiple scattering and finite geometry are performed by using Monte-Carlo method. The experimental results are compared with the available data and the calculations of optical model of spherical nucleus.更多还原
