Abstract Collective bands in77Kr have been studied with the help ofγ singles spectra,γγ coincidences,γ ray angular distributions and recoil-distance life time experiments measured during the irradiation of63Cu and64Ni targets with16O ions. Positive and negative parity bands with the following level energies, spins, and parities have been found: g.s. 5/2+; 150.1 keV 7/2+; 279.1 9/2+; 784.8 11/2+; 1003.7 13/2+; 1660.5 15/2+; 1919.1 (17/2+); 66.5 keV (3/2)−; 245.3 (5/2)−; 499.6 (7/2)−; 799.5 (9/2)−; 1177.3 (11/2)−; 1569.9 (13/2)−; 2063.2 (15/2)−. A mean life time of 170±17 nsec for the 66.5 keV state was measured withγγt coincidences and a mean life time of 48±13 psec for the 245.3 keV state was obtained with a recoildistance Doppler shift measurement.
