N2 - We consider the effect in neutron stars of nucleon decay catalyzed by grand unified monopoles. Invoking observational limits on the diffuse ultraviolet and X-ray background, we obtain a bound on the product of the cross section σ for the catalysis process and the interstellar monopole flux Φ, 〈σβ〉 Φ {less-than or approximate} 10-27cm2 × 10-25cm-2s-1sr-1. If, as Rubakov and Callan have recently suggested, 〈σβ〉 is a typical strong interaction cross section, then this bound is stronger by nine orders of magnitude than previous limits on the monopole flux.
