We studied multinucleon transfer processes in near barrier collisions of heavy nuclei with a goal to investigate possible population of isotopes along the N=126 shell. In particular we investigated deep inelastic transfer (DIT) reactions in the heavy collision system Ni+Pb at 5.0 MeV/u using the velocity filter SHIP and its detection system (see [1]).The(More)
The first measurement of the momentum distribution for one-neutron removal from (24)O at 920A MeV performed at GSI, Darmstadt is reported. The observed distribution has a width (FWHM) of 99 +/- 4 MeV/c in the projectile rest frame and a one-neutron removal cross section of 63 +/- 7 mb. The results are well explained with a nearly pure 2s_{1/2} neutron(More)

A measurement of the reduced transition probability for the excitation of the ground state to the first 2+ state in 104Sn has been performed using relativistic Coulomb excitation at GSI. 104Sn is the lightest isotope in the Sn chain for which this quantity has been measured. The result is a key point in the discussion of the evolution of nuclear structure(More)
At the FAIR facility, the projectile fragment separator Super-FRS will provide beams of exotic nuclei with unprecedented intensity. The new Collector Ring (CR) is optimized to accept large-emittance secondary beams provided by the Super-FRS. High-precision mass measurements of exotic nuclei with life-times as short as a few tens of microseconds will be(More)
The core-excited isomer in fully-ionized Sb has been directly studied for the first time by applying the novel technique of isochronous mass spectrometry at GSI. The neutron-rich nuclides in high charge states were produced by projectile fission of 411 MeV·A U ions, separated in flight by the fragment separator (FRS) and stored in the isochronous storage(More)
Previously unknown isotopes (30)Ar and (29)Cl have been identified by measurement of the trajectories of their in-flight decay products (28)S+p+p and (28)S+p, respectively. The analysis of angular correlations of the fragments provided information on decay energies and the structure of the parent states. The ground states of (30)Ar and (29)Cl were found at(More)

We report on the first measurement of the beta+ and orbital electron-capture decay rates of 140Pr nuclei with the simplest electron configurations: bare nuclei, hydrogenlike, and heliumlike ions. The measured electron-capture decay constant of hydrogenlike 140Pr58+ ions is about 50% larger than that of heliumlike 140Pr57+ ions. Moreover, 140Pr ions with one(More)
