Abstract
The Doppler-Shift Attenuation Method has been used to extract transition qu adrupole moments of high-spin bands in the N = 74 isotones Pr-133, Ce-132 a nd La-131, produced in the Cl-37 + Mo-100 reaction. The results appear to h e configuration dependent and, for Pr-133 and Ce-132, the involvement of Om ega = 1/2 Vh(9/2) and vf(7/2) intruder orbitals appears to enhance the coll ectivity at high spin (I > 25 h).
