Title: Experiments on Nuclear Structure and Synthesis of Superheavy Elements at SHIP

Abstract

Experiments to synthesize isotopes of heaviest elements and to investigate as well their production mechanisms as their nuclear properties have been performed during the past three decades at the velocty filter SHIP. Isotopes of six so far unknown elements with atomic numbers Z = 107-112 have been identified, excitation functions for production of transactinide isotopes in so-called 'cold' fusion reactions, using Pb- or Bi- targets and 'medium' heavy projectiles from 50Ti to 64Ni have been measured. In recent years experiments also concentrated on nuclear structure investigations by means of evaporation residue (ER)-{gamma}- or {alpha}-{gamma}-decay spectroscopy resulting in systematic studies of low lying Nilsson levels in odd mass nuclei and identification of high lying (E* > 1 MeV) isomeric states in neutron deficient nobelium isotopes.
