摘要：

A Doppler shift attenuation measurement has been carried out to determine the collectivity of the superdeformed band in 150Gd. The data was found to be consistent with a constant inband quadrupole moment of 17 +/- 3 eb. This corresponds to a quadrupole deformation of beta-2 almost-equal-to 0.58. In addition the measurement has resolved important questions regarding the de-excitation of the band, confirming the rapid de-excitation of the superdeformed band in 150Gd with more than 80% of the band intensity being lost over one transition.
