摘要

LAMIS 是一种已知的轻元素（如 B、C 等）同位素偏移分析技术。对其在重分子中的应用研究较少。我们证明，在激光诱导等离子体中，氧化钆的振动和旋转跃迁 A(1-0)、A(1-2) 和 A(2-1) 在天然氧化钆、156氧化钆和 158氧化钆的发射中表现出明显的差异。绝对值在 0.4-0.5 cm-1 范围内。除了具有足够的光谱分辨率之外，Demon HR 双梯度单色仪还证明了其在稀土元素同位素分析方面的灵敏度。

Isotopic shift analysis of GdO by LAMIS

LAMIS is a known technique for isotopic shift analysis of light elements, such as B, C, etc. Its application for heavy molecules has been studied less. We proved that vibrational and rotational transitions A(1–0), A(1–2), and A(2–1) of GdO in Laser-Induced Plasma exhibit apparent differences between natural GdO, ¹⁵⁶GdO, and ¹⁵⁸GdO emissions. The absolute values are in the 0.4–0.5 cm⁻¹ range. Besides its adequate spectral resolution, the Demon HR Double Echelle Monochromator proved its sensitivity for isotopic analysis of Rare Earth Elements.
