Finally … excitement in Rutherfordium !
After many years of hard work and in particular the development of an enriched 50Ti beam, it has finally been possible to perform in-beam spectroscopy of the super heavy nucleus 256Rf (Rutherfodium in honour of E. Rutherford who discovered the nucleus in 1911). The photons emitted by the 256Rf nucleus were detected in the multidetector JUROGAM II, which was coupled to the recoil separator RITU at the Department of Physics of the University of Jyväskylä.
The experiment was carried out in September 2011 (100 years after Rutherford’s discovery !) and lasted for 3 weeks. Researchers from ten worldwide institutes, including 3 French ones (CSNSM, IPHC and IRFU) took part in the experiment. This nucleus is the heaviest studied in such a manner and the observed rotational band proves that this nucleus is still very much deformed.
