Spectroscopy of element 115 decay chains.
A high-resolution α, x-ray, and γ-ray coincidence spectroscopy experiment was conducted at the GSI Helmholtzzentrum für Schwerionenforschung. Thirty correlated α-decay chains were detected following the fusion-evaporation reaction 48Ca + 243Am. The observations are consistent with previous assignments of similar decay chains to originate from element Z=115. For the first time, precise spectrosc...
متن کاملSuperheavy-element spectroscopy: Correlations along element 115 decay chains
Following a brief summary of the region of the heaviest atomic nuclei yet created in the laboratory, data on more than hundred α-decay chains associated with the production of element 115 are combined to investigate time and energy correlations along the observed decay chains. Several of these are analysed using a new method for statistical assessments of lifetimes in sets of decay chains.
متن کاملAlpha decay chains from superheavy nuclei
Magic islands for extra-stable nuclei in the midst of the sea of fission-instability were predicted to be around Z=114, 124 or, 126 with N=184, and Z=120, with N=172. Whether these fissionsurvived superheavy nuclei with high Z and N would live long enough for detection or, undergo alpha-decay in a very short time remains an open question. Alpha-decay half lives of nuclei with 130 ≥ Z ≥ 100 have...
متن کاملPairing and Α-decay
Received Revised Nuclear pairing interaction plays a crucial role in both macroscopic-microscopic and fully macroscopic descriptions of nuclei. In the present study we discuss different pairing interactions (monopole and δ pairing forces) and the methods allowing for the particle number symmetry restoration in addition to the customary BCS treatment of pairing correlations in the context of α-d...
متن کاملTheoretical Investigations of Chemical Reactivity of Element 113
The heaviest element identified chemically is Z=112. Using the gas-phase thermochromatography technique, its volatility, i.e., the adsorption enthalpy, ∆Hads, on gold plated detectors located along the chromatography column was investigated and compared to that of Hg [1]. Very recently, results of the first chemical studies on element 114 using the same technique were reported [2,3]. Both eleme...
