从多次散射的理论框架，获得反质子的光学势，这一光学势能很好地描述从轻核至重核在整个能区的弹性散射实验。
From the framework of the multiple scattering theory, we obtain the antiproton-nucleus optical potential that can best describe the experimental elastic scattering data.
然后说势能，位能其实就是，由电子和原子核之间的库仑引力而形成的能量。
And then the potential energy, the energy is stored here due to the coulombic force of attraction between the electron and the nucleus.
