The reaction 54Cr$ + $248Cm was investigated at the velocity filter SHIP at GSI, Darmstadt, with the intention to study production and decay properties of isotopes of element 120. Three correlated signals were measured, which occurred within a period of 279ms. The heights of the signals correspond with the expectations for a decay sequence starting with an isotope of element 120. However, a complete decay chain cannot be established, since a signal from the implantation of the evaporation… 

α decay and cluster radioactivity of nuclei of interest to the synthesis of Z=119 , 120 isotopes

Super-heavy nuclei of interest for the forthcoming synthesis of the isotopes with Z=119, 120 are investigated. One of the very interesting latest experiments was performed at the velocity filter SHIP

Eighty years of research on super-heavy nuclei

Professor Walter Greiner, our mentor, colleague, and friend, passed away in the age of eighty. During his lifetime, the search for elements beyond uranium started and elements up to the so far

Studies on the synthesis of isotopes of superheavy element Lv (Z = 116)

Abstract.The probable projectile-target combinations for the synthesis of superheavy nucleus 296Lv found in the cold valley of 296Lv have been identified by studying the interaction barrier of the

Studies on heavy particle radioactivity from superheavy nuclei leading to doubly magic 304120 daughter nuclei

The alpha decay and heavy particle radioactivity of the isotopes of even–even superheavy nuclei with Z = 122–132 have been studied within Coulomb and proximity potential model. The predicted

Search for elements 119 and 120

A search for production of the superheavy elements with atomic numbers 119 and 120 was performed in the Ti50+Bk249 and Ti50+Cf249 fusion-evaporation reactions, respectively, at the gas-filled recoil

Synthesis and properties of isotopes of the transactinides

Abstract Isotopes of transactinide elements have to be synthesized in nuclear reactions with light or heavy beam particles. The efficient production by neutron capture and subsequent β− decay as it

Fusion-fission probabilities, cross sections, and structure notes of superheavy nuclei

Fusion – fission probabilities in the synthesis of heaviest elements are discussed in the context of the latest experimental reports. Cross sections for superheavy nuclei are evaluated using the

A comparative study of α-decay and spontaneous fission for Z = 120 superheavy isotopes

In this study, we have investigated the α-decay chains of even–even superheavy nuclei Z = 120 in the range of 290 ≤ A ≤ 304. The Hartree–Fock–Bogoliubov model is used to calculate the binding energy

Some critical remarks on a sequence of events interpreted to possibly originate from a decay chain of an element 120 isotope
