ResumoBy reconstructing an M X-ray spectrum from 163Ho per atom per second using two spectra SM1 and SM2, the M X-ray spectra of dysprosium when there is one vacancy in the M1 and M2 subshell, the partial decay constants λM1 and λM2 were determined. Using λM1, λM2 and λ1 (total decay constant), an upper limit of 550 eV was obtained for the mass of the electron neutrino.
