Spectroscopic Tools Applied to Element Z = 115 Decay Chains

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...

Superheavy-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.

Gamma-Ray Spectroscopy of Nuclei Along the Z=115 Decay Chain

During the past decade correlated α-decay chains have been observed in several independent experiments using Ca-induced fusion-evaporation reactions on actinide targets [1]. These are interpreted to originate from the production of isotopes with proton numbers Z = 113-118. In a recent experiment at the GSI Helmholtzzentrum für Schwerionenforschung GmbH in Darmstadt, Germany, using the reaction ...

Higher order corrections to Z–decay∗

Recent developments in the field of automatic computation of Feynman diagrams using asymptotic expansions are reviewed. The hadronic decay rate of the Z–boson is taken as an example for their physical application.
