dc.description.abstract | <p>Excited states in the neutron-deficient transitional nuclei ¹¹²ʼ¹¹⁴ʼ¹¹⁶Te have been studied by means of heavy-ion (H.I.,xnypzα) reactions. Levels up to spin 22n at excitation energies of up to 9 MeV were established using Υ-Υ coincidence, Υ-ray angular distribution, Υ-ray excitation function and, in the case of ¹¹²Te, Υ-Υ-time measurements. In addition, the characteristics of a number of fusion-evaporation reactions leading to residual nuclei in this region have been analyzed and compared to theoretical predictions.</p> <p>Positive-parity structures above spin 4⁺, 8⁺ and 14⁺ in ¹¹²Te, ¹¹⁴Te and ¹¹⁶Te respectively as well as negative-parity bands based on 8⁽⁻⁾ and 9⁽⁻⁾ states are reported for the first time. Positive- and negative-parity band structures up to spin 16⁺ are compared to the predictions of a number of models usually applied to transitional nuclei, and interpreted in terms of valence single-particle plus collective vibrational degrees of freedom. At higher spins (12n to 22n) no strong evidence for rotational structure is seen.</p> <p>As part of the data analysis for the present work, a numerical deconvolution method appropriate to Υ-ray spectra is presented in the Appendix.</p> | en_US |
