Abstract: The paper contains experimental results for the intensity
of the continuous spectrum in the negative glow region of a glow discharge. It is
shown that at low pressures and low degree of ionization d ~ 10-6 the electron
scattering on neutral particles makes the main contribution to the intensity of
the continuous spectrum. It was found that the measured value of the intensity of
the continuous spectrum exceeded the calculated value 102-104
times, with the largest discrepancy observed at the end of the negative glow
region.
Key words: bremsstrahlung emission,
continuum spectrum, glow discharge.
