Study of quadrupole moments of superdeformed bands in 145Gd

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 e b and Q 0 =13.2±1.0 e b, respectively. The configuration assignments based on the quadrupole moments are π 6 1 π [404]9/2 ν [514]9/2 ν 7 0 for the yrast superdeformed band and π 6 2 ν [642]5/2 ν 7 0 for the first excited superdeformed band between the two known crossings.
