The spectroscopic properties of high-pressure xenon

The density and temperature dependences of the mean energy to form an ion pair, W-value, and the intrinsic energy resolution, ΔE 0, of high-pressure Xe were investigated with a parallel plate ionization chamber. A temperature and pressure independent technique to monitor the density of Xe was used....

Description
Summary:The density and temperature dependences of the mean energy to form an ion pair, W-value, and the intrinsic energy resolution, ΔE 0, of high-pressure Xe were investigated with a parallel plate ionization chamber. A temperature and pressure independent technique to monitor the density of Xe was used. Changes in both the W-value and ΔE 0 were observed, as a function of temperature between 14°C and 70°C and density between 0.12 and 1.7 g/cm 3, and these were found to correlate with the formation of energy bands in Xe, for the former, and changes in the recombination rate, for the latter. Qualitative analysis of the experimental results is presented.
