48Ca+249Bk fusion reaction leading to element Z = 117: long-lived α-decaying 270Db and discovery of 266Lr.
TLDR
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.
TLDR
For the first time, precise spectroscopy allows the derivation of excitation schemes of isotopes along the decay chains starting with elements Z>112.
Superheavy element flerovium (element 114) is a volatile metal.
TLDR
A gas-solid chromatography study of the adsorption of Fl on a Au surface points to the formation of a metal-metal bond of Fl with Au, the least reactive element in the group, but still a metal.
Prospects of A and Z identification experiments at LBNL
The identification of six new elements within the last 15 years and with proton numbers, Z = 113–118 has transformed the heavy element field. However, one key piece of information on these nuclei…
Decay spectroscopy of element 115 daughters : 280 Rg → 276 Mt and 276 Mt → 272
TLDR
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.
Gas chemical investigation of hafnium and zirconium complexes with hexafluoroacetylacetone using preseparated short-lived radioisotopes
Abstract Volatile metal complexes of the group 4 elements Zr and Hf with hexafluoroacetylacetonate (hfa) have been studied using short-lived radioisotopes of the metals. The new technique of physical…
Multi-quasiparticle states in (256)Rf
Excited states in (256)Rf were populated via the Pb-208(Ti-50,2n) fusion-evaporation reaction. Delayed gamma-ray and electron decay spectroscopy was performed and three isomeric states in (256)Rf h…
First Superheavy Element Experiments at the GSI Recoil Separator TASCA: The Production and Decay of Element 114 in the 244Pu(48Ca,3-4n) Reaction
Experiments with the new recoil separator, Transactinide Separator and Chemistry Apparatus (TASCA), at the GSI were performed by using beams of Ca-48 to irradiate targets of Pb206-208, which led to…
Production and decay of element 114: high cross sections and the new nucleus 277Hs.
TLDR
The fusion-evaporation reaction 244Pu(48Ca,3-4n){288,289}114 was studied at the new gas-filled recoil separator TASCA and a previously unobserved α branch in 281Ds was observed (probability to be of random origin from background: 0.1%).
New superheavy element isotopes: ²⁴²Pu(⁴⁸Ca,5n) ²⁸⁵114.
The new, neutron-deficient, superheavy element isotope ²⁸⁵114 was produced in ⁴⁸Ca irradiations of ²⁴²Pu targets at a center-of-target beam energy of 256 MeV (E*=50  MeV). The α decay of ²⁸⁵114was…
