空气中非热气体排放的极端紫外线发射的模型：分子氮的b（1）-X（0）谱带

我们对分子氮N 2的Birge-Hopfield I带系统的（v'= 1，v''= 0）带进行建模，即## IMG ## [http://ej.iop.org/images/0953 -4075 / 53/19/195204 / baba77cieqn1.gif] {$ {b} ^ {1} {{\ Pi}} _ {u} \ left（{v} ^ {\ prime} = 1 \ right）-{ X} ^ {1} {{\\ Sigma}} _ {g} ^ {+} \ left（{v} ^ {\ prime \ prime} = 0 \ right）$}，是由低压空气中的非热气体排放产生的。特别地，我们计算了在室温下热平衡的N 2的电子冲击激发速率，使其达到N 2的旋转能级J'<31（b 1Πu，v'= 1，J'）。随后，我们计算了从上述旋转能级到## IMG ## [http://ej.iop.org/images/0953-4075/53/19/195204/baba77cieq。]的辐射跃迁产生的发射线强度。 。] {$ {\ mathrm {N}} _ {2} \ left（{X} ^ {1} {{\ Sigma}} _ {g} ^ {+}，{v} ^ {\ prime \ prime} = 0，
