Abstract
EXO-200 is a single phase liquid xenon detector designed to search for neutrinoless double-beta decay of . Here, we report on a search for various Majoron-emitting modes based on 100 kg yr exposure of . A lower limit of at 90% C.L. on the half-life of the spectral Majoron decay was obtained, corresponding to a constraint on the Majoron-neutrino coupling constant of .
