The rate for proton decay to the e+γ mode is calculated. Although its branching ratio is of order α, its ratio to observable e+π0 correlated decays is 1 8 to 1 40. Observable numbers of p → e+ + γ decays can occur and would provide constraints on the proton wave function at the origin and grand unified parameters independent of hadron final state uncertainties. © 1981.
