用激光共振吸收技术测定了电子激发钕蒸气在真空膨胀过程中的弛豫速率。进入地面和1128‐cm−1水平的种群显著增加。分析表明，受激亚稳原子与电子之间的相互作用比原子-原子碰撞对弛豫更重要。钕的最终种群似乎是在低于熔体表面温度的温度下冻结的。
The laser resonance absorption technique has been used to determine the relaxation rate of electronically excited neodymium vapor during its expansion into vacuum. Significant increases of population into ground and 1128‐cm−1 levels were found. Analysis shows that interaction between excited metastable atoms and electrons are much more important for relaxation than atom‐atom collisions. The final population of neodymium appears to be frozen at a temperature lower than the surface temperature of melt.
