The basis exponents and coefficients for N₂

<b>Table 1.</b> The basis exponents and coefficients for N₂. <strong>Abstract</strong> We have determined the multiply differential cross sections (MDCS) of the vertical photo-double ionization of diatomic nitrogen with coincidence detection of the ejected electrons, for fixed and random orientations of the internuclear axis, using the correlated product of two two-centre continuum Coulomb functions for the description of the two ejected electrons, which satisfies the exact asymptotic conditions. To verify our procedure, we have applied it to the photo-double ionization of diatomic hydrogen for which many experimental and theoretical results are available. Our results on diatomic hydrogen show the influence of the initial state correlation. In the case of diatomic nitrogen only, the photo-double ionization of the 3σ_<em>g</em> orbital is considered resulting in the ¹Σ_<em>g</em> state of the residual N_2^{2+} dication. The case of the nearby ³Π_<em>u</em> final state having an open shell configuration will be considered in a future paper. Our results confirm the symmetry properties of the MDCS and give the optimal ejection angles. A comparison is also made with results obtained by the Gaussian parametrization method.**表1** 氮气（N₂）的基组指数与系数 **摘要** 本研究采用满足精确渐近条件的双中心连续库仑函数关联乘积形式描述两个出射电子，结合出射电子符合探测技术，针对核间轴固定与随机取向的双原子氮体系，计算得到其垂直光双电离过程的多重微分散射截面（multiply differential cross sections, MDCS）。为验证所采用的计算流程，我们将其应用于已有大量实验与理论结果的双原子氢光双电离过程，所得结果揭示了初态关联效应的影响。针对双原子氮体系，本工作仅考虑3σ_g轨道的光双电离过程，最终得到残留双电荷阳离子N₂²⁺的¹Σ_g态。对于邻近的具有开壳层构型的³Π_u末态，相关研究将在后续论文中展开。本研究结果验证了多重微分散射截面的对称性性质，并给出了最优出射角；同时还与高斯参数化方法得到的结果进行了对比。
