Properties of superdeformed band population in the A≈130 region

Intensities of transitions in both yrast and excited superdeformed bands in 132Ce and 131Ce have been measured for different compound nuclear entry conditions. The reaction of 100Mo(36S, xn) was used at six different bombarding energies of 135, 142, 150, 155, 160, and 170 MeV, covering a wide range in compound nuclear lmax (47–75ħ) and excitation energy (69–95 MeV). Three superdeformed bands were populated in the reactions, namely the 132Ce yrast band, 131Ce yrast band, and the 131Ce excited band. Intensity measurements were made as a function of bombarding energy and various population effects were observed. Many of these effects are difficult to explain within the framework of the current picture of superdeformed band feeding.
