Abstract

The cross section for the reaction (Formula presented) has been measured at (Formula presented) (Formula presented) (Formula presented) (Formula presented) and (Formula presented) by Fermilab experiment E835. A non-magnetic spectrometer is used to identify the (Formula presented) final states generated by the antiproton beam intersecting an internal hydrogen gas jet target. From the analysis of the 144 observed events, new high-precision measurements of the proton magnetic form factor for timelike momentum transfers are obtained.
