We report the first observation of line emission resulting directly from charge-exchange recombination of medium-Z elements injected into a PLT discharge. Transitions due to the radiative cascade immediately following charge-exchange of He-like Al and Sc were observed. One of the newly observed lines, AlXI 3209, offers a convenient spectroscopic and medium-Z charge-exchange diagnostic due to its long (air) wavelength. Spatial scans provided information on the profile of the neutral beam in the plasma.
