The temperature dependence of the rate constants for the deexcitation of Ne() by N2 has been measured in the temperature range from 136 K to 294 K using a pulse radiolysis method as combined with time-resolved optical absorption spectroscopy and thus the collisional energy dependence of the deexcitation cross sections is obtained. The deexcitation cross sections are in the range of 6.1- 9.3 for Ne() and almost constant or increase slightly with increasing the collisional energy. The deexcitation cross sections are compared with those various reported methods. The results of Ne() by N has been also compared with the results of Ne() by N. The comparison shows that more experimental and theoretical research works should be needed to clarify the deexcitation mechanism.
