Abstract
The nuclei Sn-106 and Sn-108 have been populated using the Fe-54(Ni-58 ,alpha 2p) and Fe-54(Ni-58,4p) reactions, respectively, at a beam ener gy of 243 MeV and the gamma rays have been detected using the Gammasph ere array. Two ''rotation-like'' structures consisting of magnetic dip ole transitions have been observed in each of the nuclei. The bands ca n be interpreted, using the Tilted Axis Cranking model, as examples of magnetic rotation. The calculations show excellent agreement with the data for Sn-108. However, for the lighter isotope, Sn-106, the model is unable to reproduce the experimental B(M1)/B(E2) ratios. Reasons fo r this discrepancy are discussed. (C) 1998 Elsevier Science B.V.
