Description
E835 at Fermilab reports the angular distribution for the reaction p-barp→ e+e- at ψ' resonance leading to a measurement of the proton electromagnetic form factor ratio (|(GE/GM)|). Based on a clean sample of 6844 events for the exclusive reaction, we obtained a preliminary measurement of λ = 0.67-0.14+0.15 ±±0.07 and |(GE/GM)| 0.87-0.24+0.25 at s = 13.59 GeV2
