Abstract
The aim of this work is the study of {sup 151}Tb and {sup 152}Tb nuclei submitted to increasing speeds using the EUROGAM (phase I) multi-detector. The production of high angular momentum excited nuclei is obtained during {sup 130}Te({sup 27}Al,xn) fusion-evaporation reaction with a 154 MeV bombardment energy. For {sup 151}Tb nucleus, the diagram of high spin normal deformation levels is first determined to allow the analysis of bonds between SD structures and normally deformed states. In addition to the two SD bands already described for {sup 151}Tb nucleus, 8 new SD bands are described (6 for {sup 151}Tb nucleus and 2 for {sup 152}Tb nucleus) using triple and quadruple events analysis. The SD structure analysis gives important informations about nuclear superdeformation in this mass region, in particular about SD bands de-excitation, intrinsic configuration in the second potential well, and gamma transition energy degeneration between twin SD bands. A detailed description of EUROGAM 4{pi}{gamma} multi-detector (phase I and II), which comprises 42 Ge detectors with Compton suppression, is given. (J.S.). 98 refs., 100 figs., 22 tabs.
