Obtaining monochromatic beams of radioactive nuclei with energies near the Coulomb barrier on joint institute of nuclear research accelerator complex DRIBs

Two methods for obtaining monochromatic beams of radioactive nuclei with energies near the Coulomb barrier on Joint Institute of Nuclear Research accelerator complex DRIBs are described. In the first method, an MSP-144 magnetic spectrometer was used as the monochromator of low-energy 6 He beam obtained after passing through an energy degrader. In the second method, a specially developed probe was used for experiments with the internal beam of the DRIBs complex post-accelerator (the U-400 cyclotron).
