“…23 Various chemical methods were used, as well as the two on-line separators, SASSY and SHIP . 1 As far as detection of superheavy nuclei is concerned, the result of the experiment was negativ~. However, the gas-filled separator was shown to be capable of fairly background-free operation, and an upper limit for the production cross section of roughly 3 X 10-3 4 cm 2 was obtained for a half-life range of a few microseconds to several seconds.…”

“…The setup is schematically shown in 1. In the RADRIS method, nobelium ions are separated from the primary beam by the separator for heavy ion reaction products (SHIP [18,19]) and slowed down in 100 mbar ultra-pure argon gas. The fraction of the stopped ions that remains in a charged state is accumulated on a tantalum filament.…”

Abstract. Laser spectroscopy of the heaviest elements provides high-precision data on their atomic and nuclear properties. For example, atomic level energies and ionization potentials allow us to probe the influence of relativistic effects on their atomic structure and to benchmark state-of-the-art atomic structure calculations. In addition, it offers an alternative route to determine nuclear properties like spins, magnetic moments and quadrupole moments in a nuclear model-independent way. Recently, a sensitive method based on resonant laser ionization has been applied to nobelium isotopes around N = 152 at GSI Darmstadt. In pioneering experiments, several atomic states have been identified extending the reach of laser spectroscopy beyond fermium. In this contribution, the main achievements and future perspectives are briefly summarized.

“…SHIP is a kinematic separator for reaction recoils frorn thin targets irradiated by beams from the heavy-ion linear accelerator UNILAC at GSI [3]. It is optimized for the separation of heavy elements produced by fusion of projectiles from A = 40 to 80 with heavy target nuclei such as lead or bismuth.…”

Abstract. First off-line tests at the ion trap facility SHIPTRAP took place. The facility is being set up to deliver very clean and cooled beams of singly-charged recoil ions produced at the SHIP velocity filter at GSI, Darmstadt. SHIPTRAP consists of a gas cell for stopping and thermalizing high-energy recoil ions from SHIP, an rf ion guide for extraction of the ions from the gas cell, a linear rf trap for accumulation and bunching of the ions, and a Penning trap for isobaric purification. The physics programme of the SHIPTRAP facility comprises mass spectrometry, nuclear spectroscopy, laser spectroscopy and chemistry of transeinsteinium elements. The progress in testing the subsystems separately and in combinations is reported.
