在GSI Helmholtzzentrum f<e:1> r Schwerionenforschung Darmstadt,升级后的TASISpec装置,加上一个veto DSSD和新的compx探测器-锗阵列,与充气反冲分离器TASCA一起用于研究flerovium(114号元素)的衰变链。随着新分析技术的发展,探测器的升级提高了TASISpec装置测量α-光子一致性的灵敏度。这些改进已经通过测试反应进行了评估。用48 Ca+ 206,207 Pb的反应验证了DSSD的透射到注入和靶段与α-衰变的相关性。利用48 Ca+ nat Hf反应产生若干具有多个-α衰变链的短寿命原子核,研究堆积事件反褶积。
An upgraded TASISpec setup, with the addition of a veto DSSD and the new Compex detector-germanium array, has been employed with the gas-filled recoil separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung Darmstadt, to study flerovium (element 114) decay chains. The detector upgrades along with development of new analytical techniques have improved the sensitivity of the TASISpec setup for measuring α-photon coincidences. These improvements have been assessed with test reactions. The reaction 48 Ca+ 206,207 Pb was used for verification of experimental parameters such as transmission to implantation DSSD and target-segment to α-decay correlations. The reaction 48 Ca+ nat Hf was used to produce several short-lived nuclei with multiple-α decay chains to investigate pile-up event deconvolution.
