Résumé :
In the past ten years or so, significant progress has been made in in-beam and decay spectroscopic studies of heavy elements beyond uranium, particularly in the transactinide region of the nuclear chart. Nuclei in this region can be produced with sufficient cross-section that they are now possible to study in some detail. Such detailed studies are essential in order to better understand the structure of nuclei containing an extreme number of protons, and to help provide improved theoretical predictions of the properties of superheavy elements. In in-beam studies, gamma-ray spectroscopic techniques are usually employed in order to obtain information about excited state structures. In such heavy nuclei, internal conversion is a competing process and indeed dominates in the decay of low-energy electromagnetic transitions. The present talk will introduce recent in-beam studies and trace the development of such studies at JYFL, with emphasis on electron spectroscopic studies.
