2、 Physics Field: Nuclear Physics Grade: 2006 Abstract Based on the α -particle model of 12C nucleus, 12 d C ?elastic scattering have been evaluated within the framework of Glauber multiple scatterin

3、g theory. The Glauber multiple-scattering theory is widely applied to study hardon-nuclei and nuclei-nuclei scattering. In this theory, hardon-nuclei and nucleus-nucleus elastic scattering can be described successful by

4、using two-particles scattering amplitude data as input. We choose two types of deuteron form factor, one is the sin of Gaussian form, and the other is the sum of Gaussians form. For form factor of 12C nucleus, we choose
