Paper Abstract

The opto-galvanic signals from oriented and aligned ensemble of atoms are detected and compared. A Ne/Ca hollow cathode discharge (HCD) lamp is used as a plasma medium illuminated with He-NE laser. The measurements are performed at low gas pressure 4 Torr in range 0,3 ÷ 8 mA discharge current. The established differences in signals are ascribed to proper coherent conductivity corresponding to oriented and aligned ensembles. Another kind of comparison is made depending on working I-V point.
