Mean lifetimes have been measured for superdeformed bands of (145)Gd with the Doppler-shift attenuation method. The extracted quadrupole moments of the yrast and first excited superdeformed bands are Q(0) = 11.8 +/- 0.8 eb and Q(0) = 13.2 +/- 1.0 eb, respectively. The configuration assignments based on the quadrupole moments are pi 6(1)pi[404]9/2 nu[514]9/2 nu 7(0) for the yrast superdeformed band and pi 6(2)nu[642]5/2 nu 7(0) for the first excited superdeformed band between the two known crossings.

Abstract
Mean lifetimes have been measured for superdeformed bands of (145)Gd with the Doppler-shift attenuation method. The extracted quadrupole moments of the yrast and first excited superdeformed bands are Q(0) = 11.8 +/- 0.8 eb and Q(0) = 13.2 +/- 1.0 eb, respectively. The configuration assignments based on the quadrupole moments are pi 6(1)pi[404]9/2 nu[514]9/2 nu 7(0) for the yrast superdeformed band and pi 6(2)nu[642]5/2 nu 7(0) for the first excited superdeformed band between the two known crossings.
