回顾了世界各实验组在类时和类空过程中电磁形状因子的测量状况,根据BESⅡ上R值扫描所获取的2.0～3.0 GeV各能量点的数据,探讨如何在BEs上测量类时过程的质子电磁形状因子,最后结合BESⅢ给出对该实验的展望.

This paper gives a review of measurements of proton elecmagnetic form factors in spacelike and timelike region, repectively. The approach to measure proton elecmagnetic form factors in timelike region on BESⅡ with R scan data between 2.0~3.0 GeV is presented. Finally, it studies the feasibility an...
