If, as recently proposed by Farrar and Piran, CenA is the source of cosmic rays detected above the Greisen-Zatsepin-Kuz'min cutoff, neutrons are {approx}140 more probable than protons to be observed along its line of sight. This is because the proton flux is rendered nearly isotropic by O({mu}G) intergalactic magnetic fields. With the anticipated aperture of the Southern Auger Observatory, one may expect on the order of 2neutron events/ year above 10{sup 20} eV in the line of sight of CenA.
