Abstract
EXO-200 is a single phase liquid xenon detector designed to search for neutrinoless double-beta decay of Xe136. Here, we report on a search for various Majoron-emitting modes based on 100 kg yr exposure of Xe136. A lower limit of T1/2Xe136>1.2×1024yr at 90% C.L. on the half-life of the spectral index=1 Majoron decay was obtained, corresponding to a constraint on the Majoron-neutrino coupling constant of |geeM|<(0.8-1.7)×10-5.
