Due to COVID-19, it was impossible to visit GSI for the experiment. Measurement was performed only by on-site researchers to deduce the lifetime of bound state beta decay of 205Tl, using ESR. Data analysis is in progress. The half-life has been found to be 229+-36 days. It agrees with the theoretical prediction of 122 days within 3σ. After determining the lifetime, neutrino capture cross-section thus neutrino flux will be fixed.
