Abstract
The lifetimes of five states in the ground band, from spin 6+ up to spin 14+, and of all even states in the gamma band up to spin 12+, have been measured in166Er using the recoil distance method. The reduced electric quadrupole transition probabilities have been determined from the measured lifetimes using previously measured branching ratios, and the mixing between the ground band and theγ-band has been studied. The transitional electric quadrupole moments for the ground band and theγ-band have been deduced and are discussed.
