Differential Elastic Scattering Cross Sections of 14.2MeV on Zr

The differntial elastic scattering cross sections of Zr for 14.2MeV neutrons are measured by the associated particle time-flight method at angles from 10° to 140°.The corrections for neutron flux attenuation,multiple scattering and finite geometry are performed by using Monte-Carlo method.The experimental results are compared with the available lata from other work and the theoretical calculation.
