Lifetime measurements of terminating and collective high-spin states in 155DY and 156DY
Lifetime measurements for the isotopes 155Dy and 156Dy have been extended up to spins around 40h{stroke} by the Doppler shift attenuation method in conjunction with γ-γ-coincidence measurements. Results have been obtained for the yrast band in 156Dy and for three bands in 155Dy. Strong retardations of the E2-strengt were observed for intruding terminating sequences, for which specific single parti
