Popis: Lifetime measurements for the isotopes 155 Dy and 156 Dy have been extended up to spins around 40ħ by the Doppler shift attenuation method in conjunction with γ-γ-coincidence measurements. Results have been obtained for the yrast band in 156 Dy and for three bands in 155 Dy. Strong retardations of the E2-strengt were observed for intruding terminating sequences, for which specific single particle configurations are suggested.
