本实验测量了6.8MeV质子对Cr,Co,Ni,Cu和Zn的弹性散射角分布。在其微分截面σe(θ)与库仑散射微分截面σR(θ)之比对θ的作图中显示:这几种元素A相近,也有大体相似的角分布曲线;其极大极小位置可以用kR′sinθm/2=常数表之,显示出核的粗糙结构的特征。但在大角度处,这几种质量数A相近的核,其(σe(θ))/(σR(θ))值却有显著的差异,而且偶z核的(σe(The angular distributions of 6.8 MeV protons elastically scattered by Cr, Co, Ni, Cu and Zn have been measured. The ratio of the differential scattering cross-section measured for each element to that expected from the Coulomb scattering of a point charge
