Abstract An experimental investigation of the complex γ-decay of202Pb following the β-decay of202Bi is presented. Gamma-ray energies and intensities, conversion coefficients and γ – γ-coincidences were measured using mass separated sources. The results supplement and refine previous studies. In particular the measurements of gamma-ray energies aimed at an accuracy as high as possible in order to get reliable energy relations for the ordering of the γ-transitions in a level scheme. More than 200 γ-transitions were observed. New excited levels of202Pb are proposed at 2185.0, 2235.4, 2324.9, 2360.4, 2517.3, 2916.5, 3682.2, and 3723.5 keV above the ground state. The spin value I=4 for the 1915.1 keV level of202Pb is confirmed and to the 2289.2 keV level the spin parity assignment (6)− is given.
