48Ca+249Bk fusion reaction leading to element Z = 117: long-lived α-decaying 270Db and discovery of 266Lr.
The superheavy element with atomic number Z=117 was produced as an evaporation residue in the (48)Ca+(249)Bk fusion reaction at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany and a hitherto unknown α-decay branch in (270)Db was observed, which populated the new isotope (266)Lr.
Spectroscopy of element 115 decay chains.
For the first time, precise spectroscopy allows the derivation of excitation schemes of isotopes along the decay chains starting with elements Z>112.

Electric quadrupole moments of the 21+ states in Cd100,102,104
Using the REX-ISOLDE facility at CERN the Coulomb excitation cross sections for the 0(gs)(+)-> 2(1)(+) transition in the beta-unstable isotopes Cd-100,Cd-102,Cd-104 have been measured for the first
Decay spectroscopy of element 115 daughters : 280 Rg → 276 Mt and 276 Mt → 272
This book presents a meta-history of the construction of the World Trade Center in Chicago from 1989 to 2002, a period chosen in order to explore its roots as well as specific cases up to and including the year of the Great Fire of Chicago.
108Sn studied with intermediate-energy Coulomb excitation
The unstable neutron-deficient Sn-108 isotope has been studied in inverse kinematics by intermediate-energy Coulomb excitation using the RISING/FRS experimental setup at GSI. This is the highest Z
0(gs)+ -->2(1)+ transition strengths in 106Sn and 108Sn.
The reduced transition probabilities, B(E2; 0(gs)+ -->2(1)+), have been measured in the radioactive isotopes (108,106)Sn using subbarrier Coulomb excitation at the REX-ISOLDE facility at CERN and may point towards a weakening of the N=Z=50 shell closure.
Octupole states in Tl207 studied through β decay
The β decay of 207Hg into the single-proton-hole nucleus 207Tl has been studied through γ-ray spectroscopy at the ISOLDE Decay Station (IDS) with the aim of identifying states resulting from
Nonyrast States in the Odd-odd N = Z Nucleus 62Ga
Low-lying excited states in the odd-odd N = Z nucleus 62Ga have been investigated following the heavy-ion fusion-evaporation reaction 40Ca(24Mg,pn)62Ga near the Coulomb barrier. Special emphasis is
