Query: Charge exchange reaction at high energies   The charge exchange reaction pp $\rightarrow$ n $\Delta^{++}$ at high
energies is examined. The cross section of this reaction is estimated for RHIC
and LHC energies based on data taken at the lower energies of the Intersecting
Storage Ring (ISR) at CERN. The interest of such measurements for identifying
the associated electromagnetic bremsstrahlung radiation is discussed.
