Abstract
The recent developments of the dynamic deformation model (DDM) make it readily applicable to a wide range of nuclei. The authors report a study of the even-mass tellurium isotopes from N=68 to the closed neutron shell at N=82. Within this region there is experimental evidence for nuclei with the characteristics of vibrational, rotational or gamma -unstable level sequences. They show that the model is well able to account for these features as typified by level energies, electric quadrupole moments and gamma -ray transition probabilities across this region when the only parameter which changes is the neutron number. For comparison the experimental data were also fitted to IBM-2 and the results from these fits are in general in good agreement with those from the DDM.
