The high-energy part of the alpha spectrum emitted in the bombardment of Li 7 with deuterons, was measured with a magnetic spectrometer at Ed-1.0 Mev and 0=90°. For the Li 7 (d,a)He 5 (ground state) reaction, a Q value of 14.11 ±0.08 Mev is obtained. The spectrum yields level parameters for the ground state of He 5 which are consistent with those known from n-a scattering data. No definite evidence for an a group corresponding to an excited state of He 5 was found.
