Hybrid theory calculation of simultaneous vibration-rotation excitation ine-N2scattering

Simultaneous vibration ($v$) and rotation ($j$) excitation of ${\mathrm{N}}_2$ by electron impact is calculated in the hybrid theory from the relevant formulas (involving $a$-matrix elements previously calculated). All cross sections (labeled $v,j\to v^{\prime },j^{\prime }$) involving states with $v=0,1$; $0\le j\le 1$; $0\le v^{\prime }\le 2$; $0\le j^{\prime }\le 5$ have been evaluated. A representative sample of graphical results is presented. In particular, we find large discrepancies in magnitude from the partially phenomenological theory of J. C. Y. Chen.
