Title: Recoil-α-fission and recoil-α–α-fission events observed in the reaction 48Ca + 243Am

Abstract

Products of the fusion-evaporation reaction 48Ca + 243Am were studied with the TASISpec set-up at the gas-filled separator TASCA at the GSI Helmholtzzentrum für Schwerionenforschung, Darmstadt, Germany. Amongst the detected thirty correlated α-decay chains associated with the production of element , two recoil-α-fission and five recoil--fission events were observed. The latter five chains are similar to four such events reported from experiments performed at the Dubna gas-filled separator, and three such events reported from an experiment at the Berkeley gas-filled separator. The four chains observed at the Dubna gas-filled separator were assigned to start from the 2n-evaporation channel 289 115 due to the fact that these recoil--fission events were observed only at low excitation energies. Contrary to this interpretation, we suggest that some of these recoil--fission decay chains, as well as some of the recoil--fission and recoil-α-fission decay chains reported from Berkeley and in this article, start from the 3n-evaporation channel 288 115.

Figure 1 Figure 1: (Colour online) Correlation times [(a)–(c)] and α-energy spectra [(d) and (e)] of decay chains observed in the reaction 48Ca + 243Am. The term “α energy” includes possible summation with energy deposited by conversion or Auger electrons. The black histograms are reference spectra and relate to experimental data frommore » the 96 chains associated with the 3n evaporation channel 288115 in Refs. [7,8,12]. The shaded areas in panels (a)–(c) are the corresponding time distributions. The shaded areas in panels (d) and (e) are the energy distributions derived from Monte Carlo simulations as outlined in Refs. [7,32,35]. The data points of the fourteen observed recoil-α–(α-)fission events are provided on top of each spectrum, labelled with an identifier according to Table 1. Filled symbols indicate measurement during beam-off periods. Diamonds refer to data from Ref. [12], triangles refer to data from Ref. [8], and squares and circles refer to the present data observed at 242.1 and 245.0 MeV mid-target beam energy, respectively. ‘n/a’ means ‘not applicable’, ‘escape’ denotes events with low-energy detection solely in the implantation DSSSD.« less
