Title: First experiment at TASCA towards X-ray fingerprinting of element 115 decay chains

Abstract

To identify the atomic number of superheavy nuclei produced in ⁴⁸Ca-induced fusion-evaporation reactions, an experiment aiming at measuring characteristic X-rays is being prepared at GSI, Darmstadt, Germany. The gas-filled separator TASCA will be employed, sending the residues towards the multi-coincidence detector setup TASISpec. Two ionoptical modes relying on differing magnetic polarities of the quadrupole magnets can be used at TASCA. New simulations and experimental tests of transmission and background suppression for these two focusing modes into TASISpec are presented.

Spectroscopy along flerovium decay chains. III. Details on experiment, analysis, ${}^{282}{Cn}$ , and spontaneous fission branches

Journal Article Såmark-Roth, A. ; Cox, D. M. ; Rudolph, D. ; ... - Physical Review C

Flerovium isotopes (element Z = 114) were produced in the fusion-evaporation reactions ⁴⁸Ca + ^242,244Pu and studied with an upgraded TASISpec decay station placed in the focal plane of the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. Twenty-nine flerovium decay chains were identified by means of correlated implantation, α decay, and spontaneous fission events. Data analysis aspects and statistical assessments, primarily based on measured rates of various events, which laid the foundation for the comprehensive spectroscopic information on the flerovium decay chains, are presented in detail. Various decay scenarios of an excited state observed inmore »« less

Spectroscopy along Flerovium Decay Chains: Discovery of ${}^{280}{Ds}$ and an Excited State in ${}^{282}{Cn}$

Journal Article Såmark-Roth, A. ; Cox, D. M. ; Rudolph, D. ; ... - Physical Review Letters

A nuclear spectroscopy experiment was conducted to study α-decay chains stemming from isotopes of flerovium (element Z=114). An upgraded TASISpec decay station was placed behind the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung in Darmstadt, Germany. The fusion-evaporation reactions ⁴⁸Ca + ²⁴²Pu and ⁴⁸Ca + ²⁴⁴Pu provided a total of 32 flerovium-candidate decay chains, of which two and eleven were firmly assigned to ²⁸⁶Fl and ²⁸⁸Fl, respectively. A prompt coincidence between a 9.60(1)-MeV α particle event and a 0.36(1)-MeV conversion electron marked the first observation of an excited state in an even-even isotope of the heaviest man-made elements,more »« less

Alpha-Photon Coincidence Spectroscopy Along Element 115 Decay Chains

Conference Rudolph, D. ; Forsberg, U. ; Golubev, P. ; ... - Acta Physica Polonica. Series B

Produced in the reaction ⁴⁸Ca+ ²⁴³Am, thirty correlated α-decay chains were observed in an experiment conducted at the GSI Helmholzzentrum für Schwerionenforschung, Darmstadt, Germany. The decay chains are basically consistent with previous findings and are considered to originate from isotopes of element 115 with mass numbers 287, 288, and 289. A set-up aiming specifically for high-resolution charged particle and photon coincidence spectroscopy was placed behind the gas-filled separator TASCA. For the first time, γ rays as well as X-ray candidates were observed in prompt coincidence with the α-decay chains of element 115.

Rapid extraction of short-lived isotopes from a buffer gas cell for use in gas-phase chemistry experiments, Part II: On-line studies with short-lived accelerator-produced radionuclides

Journal Article Götz, S. ; Raeder, S. ; Block, M. ; ... - Nuclear Instruments and Methods in Physics Research. Section B, Beam Interactions with Materials and Atoms

We report a novel combination of advanced gas-chromatography and detection systems coupled to a buffer-gas cell was characterized on-line to allow gas-phase chemical studies of accelerator-produced short-lived α -decaying mercury, francium, and astatine isotopes. These were produced in ⁴⁰Ar- and ⁴⁸Ca-induced nuclear fusion–evaporation reactions, subsequently isolated in the recoil separators MARS at Texas A&M University, USA, and TASCA at GSI Darmstadt, Germany, before being thermalized in a buffer-gas-stopping cell. From the latter, the nuclear reaction products were extracted into gas-phase chromatographic systems, suitable for registering α-decaying short-lived radionuclides, such as isotopes of superheavy elements.

Search for elements 119 and 120

Journal Article Khuyagbaatar, J. ; Yakushev, A. ; Düllmann, Ch. E. ; ... - Physical Review C

In this work, a search for production of the superheavy elements with atomic numbers 119 and 120 was performed in the ⁵⁰Ti + ²⁴⁹Bk and ⁵⁰Ti + ²⁴⁹Cf fusion-evaporation reactions, respectively, at the gas-filled recoil separator TASCA at GSI Darmstadt, Germany. Over four months of irradiation, the ²⁴⁹Bk target partially decayed into ²⁴⁹Cf, which allowed for a simultaneous search for both elements. Neither was detected at cross-section sensitivity levels of 65 and 200 fb for the ⁵⁰Ti + ²⁴⁹Bk and ⁵⁰Ti + ²⁴⁹Cf reactions, respectively, at a midtarget beam energy of E_lab = 281.5 MeV.
