  "abstract": "We show that wavelength measurements of individual detected optical photons may provide additional information about gamma-ray energy deposited in a CeBr$_3$ crystal when the detected-photon-count distributions overlap for nearby gamma-ray energies. Monoenergetic 662 and 629 keV gammas are used in a Geant4 simulation of a $25\\times25\\times20~\\mathrm{mm^3}$ CeBr$_3$ crystal. Assuming a light yield of $6.0\\times10^4$ photons/MeV, a wavelength-independent photon-detection efficiency of 30%, and a wavelength resolution of $σ_λ=40$ nm, we find that the fraction of photons reconstructed above 385 nm gives an event-level separation of $\\sim$ 2 standard deviations between the 662 and 629 keV event populations selected within the same $\\sim$ 1%-wide detected-photon-count interval. No timing or reconstructed interaction-position information is used. The result demonstrates, within the present simulation model, that event-dependent optical spectra can retain energy information beyond an undifferentiated photon count.",
