摘要
回顾了世界各实验组在类时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。
A review of worldwide measurements of proton electronmagneticform factors in times-like region is given. The approach to measure proton elec-tronmagnetic form factors in time-like region on BESⅡ with R scan data be-tween 2.0-3.0 GeV is presented. The feasibility and prospect of this workon BESⅢ is studied.
