Abstract

The cross sections for the deexcitation of Ne(3P1) by CH4 have been measured as a function of the mean collisional energy in the range of 17.2-36.8 meV or in the temperature range from 134 K to 285 K using a pulse radiolysis method as combined with time-resolved optical absorption spectroscopy. The deexcitation cross sections are in the range of 10-24 2 for Ne(3P1) by CH1. The behavior of the collisional energy dependence cross sections are increase slightly with increasing the collisional energy. The results are interpreted in terms of an electron exchange interaction.
