  • Scientific program of DERICA-prospective accelerator and storage ring facility for radioactive ion beam research
  • 2019
  • In: Physics-Uspekhi. - 1468-4780 .- 1063-7869. ; 62:7, s. 675-690
  • Journal article (peer-reviewed)abstract
    • Studies of radioactive ions (RIs) are the most thriving field of low-energy nuclear physics. In this paper, the concept and the scientific agenda of the prospective accelerator and storage ring facility for RI beam (RIB) research are proposed for a large-scale international project based at the Flerov Laboratory of Nuclear Reactions of the Joint Institute for Nuclear Research. The motivation for the new facility is discussed and its characteristics are briefly presented and shown to be comparable to those of advanced world centers, the so-called "RIB factories". In the project, the emphasis is made on studies with short-lived RIBs in storage rings. A unique feature of the project is the possibility of studying electron-RI interactions in a collider experiment to determine the fundamental properties of nuclear matter, in particular, electromagnetic form factors of exotic nuclei.

  • β -delayed proton emission from P 26 and S 27
  • 2017
  • In: Physical Review C: covering nuclear physics. - 2469-9985. ; 95:3
  • Journal article (peer-reviewed)abstract
    • Delayed emission of protons following β decay of neutron deficient nuclei P26 and S27 was investigated at the ACCULINNA separator in the Flerov Laboratory of Nuclear Reactions at Dubna. Ions of interest, identified in flight, were implanted into the active volume of the gaseous optical time projection chamber, which allowed us to record tracks of charged particles emitted in the decay. Total branching ratios for β-delayed proton emission and for β-delayed two-proton emission were determined. In addition, energy spectra for delayed protons below 2 MeV were established. Our findings for P26 agree with results of previous experiments. In the case of S27, however, the observed probability of delayed proton emission is an order of magnitude larger than reported in literature. Two new strong proton transitions were identified representing decays of the first two excited states of P27 to the ground state of Si26. The probability ratio of γ-to-proton emission from these states is discussed.

  • Three-body correlations in direct reactions: Example of Be 6 populated in the (p,n) reaction
  • 2018
  • In: Physical Review C. - 2469-9993 .- 2469-9985. ; 98:5
  • Journal article (peer-reviewed)abstract
    • The Be6 continuum states were populated in the charge-exchange reaction H1(Li6,Be6)n collecting very high statistics data (∼5×106 events) on the three-body α+p+p correlations. The Be6 excitation energy region below ∼3MeV is considered, where the data are dominated by contributions from the 0+ and 2+ states. It is demonstrated how the high-statistics few-body correlation data can be used to extract detailed information on the reaction mechanism. Such a derivation is based on the fact that highly spin-aligned states are typically populated in the direct reactions.
