用耦合态近似计算了10-30 K温度下C/sub 3/H/sub 2/的碰撞激发率。C/sub 3/H/sub 2/产生许多谱线对,它们的成员在频率上很接近,但来自具有不同激发能量的能级。在统计平衡计算中使用的速率来说明各种C/sub 3/H/sub 2/ line比率的激发性质和密度依赖行为。17篇参考文献。
Collisional excitation rates for C/sub 3/H/sub 2/, calculated using the coupled states approximation at temperatures of 10-30 K, are presented. C/sub 3/H/sub 2/ produces a number of spectral line pairs whose members are close together in frequency but arise from levels with different excitation energies. The rates are used in statistical equilibrium calculations to illustrate the excitation properties and density-dependent behavior of various C/sub 3/H/sub 2/ line ratios. 17 references.
