The new element 112 was produced and identified unambiguously in an experiment at SHIP, GSI Darmstadt. Two decay chains of the isotope277112 were observed in irradiations of208Pb targets with70Zn projectiles of 344 MeV kinetic energy. The isotope decays by emission of α particles with a half-life of (240−90+430)µs. Two different α energies of (11,649±20) keV and (11,454±20) keV were measured for the two observed decays. The cross-section measured in three weeks of irradiations is (1.0−0.4+1.8…

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…
The reaction 48Ca + 248Cm → 296116* studied at the GSI-SHIP
The synthesis of element 116 in fusion-evaporation reactions of a 48Ca beam with radioactive 248Cm targets was studied at the velocity filter SHIP of GSI in Darmstadt. At excitation energies of the…
Heavy and superheavy nuclei
The new elements 110, 111 and 112 were synthesized and unambiguously identified in experiments at SHIP. Due to strong shell effects the dominant decay mode is not fission, but emission of alpha…
Discovery of new element, nihonium, and perspectives (PLENARY)
A new element 113 was searched by the reaction of Zn on Bi using a gas-filled recoil ion separator at the RIKEN linear accelerator facility. Totally three decay chains due to 113 were observed. The…
Lightest isotope of Bh produced via the 209Bi(52Cr,n)260Bh reaction.
TLDR
The lightest isotope of Bh was produced in the new 209Bi(52Cr,n)260Bh reaction at the Lawrence Berkeley National Laboratory's 88-Inch Cyclotron by observation of eight correlated alpha particle decay chains in the focal plane detector of the Berkeley Gas-Filled Separator.
RESEARCH OF SUPERHEAVY ELEMENTS AT RIKEN
At RIKEN Nishina Center, a series of experiments for studying the heaviest elements has been done by using a gas-filled recoil ion separator (GARIS). Isotopes of the 112th and the 113th elements,…
Experimental survey of the production of α -decaying heavy elements in U238+Th232 reactions at 7.5–6.1 MeV/nucleon
The production of alpha particle decaying heavy nuclei in reactions of 7.5-6.1 MeV/nucleon $^{238}$U +$^{232}$Th has been explored using an in-beam detection array composed of YAP scintillators and…
The Discovery of Superheavy Elements 107–112 and of the Deformed Shell at N = 162
The production of radioactive elements at GSI Darmstadt during the last 20 years is reviewed. The development of highly sensitive separation and identification methods lead to the synthesis of…
Heavy element research at GSI — Recent results and perspectives
The nuclear shell model predicts that the next doubly magic shellclosure beyond 208Pb is at a proton number between Z=114 and 126 and at a neutron number N=184. The outstanding aim of experimental…
Frontiers of heavy element nuclear and radiochemistry
The production and half-lives of the heaviest chemical elements, now known through Z=112, are reviewed. Recent experimental evidence for the stabilization of heavy element isotopes due to proximity…

Discovery of enhanced nuclear stability near the deformed shells N=162 and Z=108.
TLDR
The decay properties of [sup 266]106 establish the existence of enhanced nuclear stability near the predicted deformed shells [ital N]=162 and [ital Z]=108, and estimated SF branches of 50% or less for both isotopes.
