Abstract :
The nuclei 106Sn and 108Sn have been populated using the 54Fe(58Ni,α2p) and 54Fe(58Ni,4p) reactions, respectively, at a beam energy of 243 MeV and the gamma rays have been detected using the Gammasphere array. Two “rotation-like” structures consisting of magnetic dipole transitions have been observed in each of the nuclei. The bands can be interpreted, using the Tilted Axis Cranking model, as examples of magnetic rotation. The calculations show excellent agreement with the data for 108Sn. However, for the lighter isotope, 106Sn, the model is unable to reproduce the experimental B(M1)/B(E2) ratios. Reasons for this discrepancy are discussed.
