Nuclear reactions of deuterons with 7Li have been used in order to determine properties of the intermediate nuclei 8Be and SHe. Of particular interest are locations and widths of the ground state and first excited state of SHe, and of the second excited state of SBe. In a complete ~-~-coincidence spectrum, however, overlapping of the coincident rates restricts very much the evaluation of such spectra. Particularly important is the velocity of the over-all center of mass which may cause unfavourable conditions for reliable determinations of the wanted data.
