Basic Ionization, Airglow and Auroral Processes

研究人员将应用理论程序定量预测分子氧中紫外辐射的瑞利和拉曼散射截面，并用于探索散射对太阳紫外辐射在大气中的透射和衰减的影响。 他将计算的横截面，并将它们插入到碰撞内核的玻尔兹曼方程，研究振动激发的影响，在减缓高能氮原子和生产的旋转和振动激发NO.他将应用量子和半经典的程序，以确定在碰撞涉及振动激发分子的能量转移的速率系数。 最后，他将定量评估亚稳态氧分子碰撞中辐射对夜间气辉中连续辐射的贡献。

The investigator will apply theoretical procedures to the quantitative prediction of cross sections for Rayleigh and Raman scattering of ultraviolet radiation in molecular oxygen, and used to explore the influence of scattering on the transmission and attenuation of solar ultraviolet radiation in the atmosphere. He will calculate the cross sections and insert them into the collision kernel of the Boltzmann equation to study the effects of vibrational excitation in the slowing of energetic nitrogen atoms and production of rotationally and vibrationally excited NO. He will apply quantal and semi-classical procedures to determine the rate coefficients for energy transfer in collisions involving vibrationally excited molecules. Finally, he will quantitatively assess the contribution of radiation involved in the collision of metastable oxygen molecules to the continuum emission present in the night airglow.
