摘要：

Radial distribution of the electric field in the cathode fall region of neon hollow cathode discharge has been derived through the observation of the linear Stark effect of the nd′(n=10-12)-3p′[1/2]1 transitions by two-step optogalvanic spectroscopy. The field strength was found to decrease monotonically from the cathode to the negative glow. The depth of the cathode fall region was 0.80±0.05 mm, and the electric field at the cathode surface was 5.2±0.2 kV/cm-values which compare with the reported values of around 3-4 mm and 3-4 kV/cm in the cathode fall region of Ne glow discharge. The difference and similarity in the values of derived parameters are discussed.
