Joint effort of the nuclear theory group at the University of Jyvaskyla and the international collaborative EXO-200 experiment paves the way for solving the reactor antineutrino flux problems. The EXO-200 collaboration consists of researchers from 26 laboratories and the experiment is designed to measure the mass of the neutrino. As a byproduct of the calibration efforts of the experiment the electron spectral shape of the beta decay of Xe-137 could be measured. This particular decay is optimally well suited for testing a theoretical hypothesis to solve the long-standing and persistent reactor antineutrino anomaly. The results of measurements of the spectral shape were published in Physical Review Letters in June 2020.
