Abstract

The pressure shifts and broadenings of a number of lines of Xe i in the visible and near infrared have been measured with xenon at pressures up to 1.5 Torr and with xenon at low pressure in helium at pressures up to 6 Torr. In most of the lines the shift due to xenon is to a longer wavelength, while that due to helium is to a shorter wavelength.
