Gamma-Ray Spectroscopy of Nuclei Along the Z=115 Decay Chain
نویسنده
چکیده
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 Ca+ Am and high-resolution charged particle and X-ray and gamma-ray coincidence spectroscopy the atomic number were measured directly in one of the isotopes in the Z = 115 decay chain [2]. The experiment used the TASISpec set-up [3] coupled to the gas-filled separator TASCA [4]. The present paper will discuss gamma-ray spectroscopy of nuclei populated along the Z = 115 decay chain.

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.

In order to understand the cause of coloration of fluorites, following experiments (UV-spectroscopy, irradiation by gamma ray and thermal bleaching) carried out on the colored and colorless fluorites from the mines of Mazandaran Province. All colored and colorless fluorites have absorption band in UV part of electromagnetic waves but deep-violet and brown fluorites have an absorption band in vi...
متن کاملSUPERNOVAE AS THE SITE OF THE r-PROCESS: IMPLICATIONS FOR GAMMA-RAY ASTRONOMY
We discuss how detection of gamma-ray emission from the decay of r-process nuclei can improve our understanding of r-process nucleosynthesis. We Ðnd that a gamma-ray detector with a sensitivity of D10~7c cm~2 s~1 at keV may detect the emission from the decay of 125Sb, 137Cs, 144Ce, Ec B 100È700 155Eu, and 194Os produced in a future Galactic supernova. In addition, such a detector may determine ...

Relativistic mean field study of the newly discovered α-decay chain of Abstract The single particle structure of the low lying levels in the nuclei belonging to the newly observed α-decay chain starting from 287 115 has been studied. Relativistic mean field calculation with two forces NL1 and NL3 has been performed in the blocked BCS approximation. Q-values for possible decay have been calculat...
