In combination with other experimental systems, this has allowed measurements over the entire 5K to 1000K range, In the semiclassical region above -100K, the behavior of the cross sections for collisions with hydrogen is more complex than comparable collisions with helium because of the additional rotational degrees of freedom in the hydrogen molecule. At low temperatures very significant increases in cross section, which are associated with the quasibound states, are observed. The new apparatus, which is particularly simple, will be described as will experimental results and their relationship to theoretical predictions. Similarities and differences with the results of helium pressure broadening work discussed in the previous talk will be presented. en_US dc.format.extent 66575 bytes dc.format.mimetype image/jpeg dc.language.iso English en_US dc.publisher Ohio State University en_US dc.title THE HYDROGEN PRESSURE BROADENING SPECTRUM OF CO, $CH_{3}F$, AND $H_{2}S$ BETWEEN 5 K AND 1000K en_US dc.type article en_US
