Visible emission spectroscopy (330--650 nm) has been performed radially and axially on a Z-pinch plasma. During the peak compression, continuum and He II line emission (468.6 nm) predominated. We report the first observation of He/sub 2/ in the post-pinch phase of a dense helium Z-pinch discharge. Axial measurements of this afterglow plasma also revealed pronounced absorption bands which cannot be identified with He/sub 2/, He I, He II, or impurities.
