    Graduate How is center of mass in a complex systems?

    Now i am suddenly confused with the concept of the center of mass. As we know , nucleus are a system of many-body,composed of nucleons. And their interactions are very complex between nucleons. I want to know, If we can observe a nuclei such as Ne20, how is the motivation of its center of mass?
