Description
EXO-200 is a double beta-decay search experiment, that was taking science data in 2011-2018. It is a liquid xenon TPC detector with 200 kg of xenon enriched to 80% in isotope $^{136}$Xe. Latest results from analysis of a full dataset will be presented. These include a limit in neutrinoless decay mode, measurement of the scintillation and ionization yields, and first results from accurate study of $^{137}$Xe beta-decay shape, which might shed some light on effective $g_A$ value. The EXO-200 detector began new era of experiments with hundred kilogram active mass. It have shown potential and maturity of the method used and can be considered as a demonstrator for a bigger detector nEXO with 5000kg of xenon that aims to reach sensitivity of $10^{28}$ years for $2\beta0\nu$ decay of $^{136}$Xe.
