We report results and analysis from a series of laser ablation experiments conducted to study high-temperature plutonium (Pu) spectroscopy and gas-phase oxidation. Time-resolved emission spectra were compared to a Pu I spectral model to infer plasma temperature. At later times in the laser-produced plasma evolution, temperatures are lower, and resonant emission bands indicative of molecular species are observed. We tentatively assign these bands to plutonium oxides (Pu_xO_y).

激光产生的plasma等离子体的光谱动力学和气相氧化

我们报告了一系列结果，并进行了一系列激光消融实验分析，以研究高温p（Pu）光谱学和气相氧化。将时间分辨的发射光谱与Pu I光谱模型进行比较，以推断等离子体温度。在激光产生的等离子体演化的后期，温度较低，并且观察到指示分子种类的共振发射带。我们暂时将这些谱带分配给氧化p（Pu _x O _y）。
