 Title    Excitation of the 210 nm Zn II Line in a Hollow Cathode He-Ne-Zn Discharge  
 Abstract    In a hollow cathode He-Zn discharge it was observed that addition of Ne stops laser oscillation at the 492.4 nm Zn II line and increases significantly the spontaneous intensity at the 210 nm Zn II line, which originates from the 4d 2 D 5/2 lower level of the laser transition. Based on a rate equation model, the cross-section of the Ne ion-Zn atom charge transfer collisions populating the 4d 2 D 5/2 level was determined. The cross-section 3.5x 10 -15 cm 2 found by us is in acceptable agreement with the value 2.3x 10" 15 cm 2 reported in the literature. This high cross-section together with existing lower level depopulation points to the possibility of obtaining laser oscillation at 210 nm in a Ne-Zn discharge.
