We perform the first amplitude analysis of decays based on data samples of electron-positron collisions recorded with the BESIII detector at center-of-mass energies between 4.128 and 4.226 GeV, corresponding to an integrated luminosity of . We report the observation of with a statistical significance greater than and determine the branching fractions and . Moreover, we measure the relative branching fraction between and to be ., which deviates from the world average value by more than . Published by the American Physical Society 2025
