A Theoretical Study of Rate Coefficients for the O + NO Vibrational Relaxation
Caridade, P. J. S. B.; Mota, V. C.; Mohallem, J. R.; Varandas, A. J. C.Quasi-classical trajectories have been integrated to study the vibrational relaxation of the O + NO(v) process as a function of the initial vibrational quantum number for T = 298 K, 1500 K, and 3000 K. Two reliable potential energy surfaces have been employed for the A‘ and A‘ ‘ doublet states of NO2. The calculated vibrational relaxation rate constants show a nearly v-independent behavior at room temperature a...
Development of a threshold positron spectrometer
Lopes, M. C. A.; Gordo, P. M.; Lima, A. P. de; Mohallem, J. R.We introduce a new positron spectroscopy experimental technique that we call threshold positron spectroscopy, by analogy with its similar threshold photoelectron spectroscopy. An apparatus that is being developed to explore this technique is described in this work. ; http://www.sciencedirect.com/science/article/B6TVT-4JW7WPW-3/1/a800a67732e0d75f39e5bc6014315e04
