Popis:	Two methods for obtaining monochromatic beams of accelerated 6He ions with energies around the Coulomb barrier on the DRIB accelerator complex at the Joint Institute for Nuclear Research (JINR) is described. In the first method, the MSP-144 magnetic spectrometer is used as a monochromator of low-energy 6He beam after its passing through an energy absorber. The energy resolution of the 6He beam, which is 500 keV, is governed by the linear dimension of the target in the focal plane (18 mm). In the other method, a special probe is used to investigate nuclear reactions with accelerated 6He beams without loss of the beam intensity. With this probe, it is possible to perform experiments on the internal beam of the postaccelerator (U-400 cyclotron) of the DRIB complex. As a result, a 6He beam with a required energy and a beam resolution of 150 keV or better is produced at the target.
