Abstract
Cross sections for the reaction (He-6,alpha) at H and C-12 nuclei and for the reaction H(He-6,Li-6) have been measured at an energy E(He-6) = 19.3 MeV, for the first time. The spectrum of a particles from the r eaction H(He-6,alpha) contains, in addition to the ground state of the triton, a resonance with an energy E = 7.0 +/- 0.3 MeV and a width G AMMA = 0.6 +/- 0.3 MeV. This resonance lies above the threshold for th e dissociation t --> n + d. It is suggested that this level has a (2n + p) configuration.
