Nuclear structure physics with Garnrnasphere

ASSTRACT. The increase in sensitivity of the new generation of ¡-ray arrays is discussed and sorne recent results obtained with Gammasphere are presented. These indude the observation of linking transitions between superdeformed and normal deformed states in IO'Hg, tH = 2 staggering, lifetime rneasurements and the use of deep-inelastic reactions as a "Y-rayspectroscopy too!. RESUMEN. Se discute la sensitividad de los sistemas de detección de rayos- ¡ de nueva generación y se presentan algunos de los resultados obtenidos recientemente con Gammasphere. Éstos incluyen la observación de transiciones entre los estados superdeformados y normales en 194Hg, ~I = 2 staggering, mediciones de vidas medias y el uso de reacciones fuertemente inelásticas como una herramienta de espectroscopía ¡. PACS: 27.60.+j; 27.80.+w; 29.30.Kv Since the discovery of radioactivity by Becquerel in 1896-y-rays have played a major role in our understanding of the atomic nucleus; as well as in many useful applications. Since the development of NaI detectors in the 1950's, the field of-y-ray spectroscopy of nuclei has evolved considerably, driven by technological advances in the production o
