Anomalous Broadening of Balmer Ha Line in Aluminum and Copper Hollow Cathode Glow Discharges

The presented results are concerned with the shape of Balmer alpha line emitted from a low pressure DC glow discharge with aluminum (Al) and copper (Cu) hollow cathode (HC) in pure H2 and Ar-H2 gas mixture. The analysis indicates that the line profile represents a convolution of Gaussian profiles re...

Summary:The presented results are concerned with the shape of Balmer alpha line emitted from a low pressure DC glow discharge with aluminum (Al) and copper (Cu) hollow cathode (HC) in pure H2 and Ar-H2 gas mixture. The analysis indicates that the line profile represents a convolution of Gaussian profiles resulting from different collision excitation processes.
