摘要
以脉冲激光束在高真空下记录第三周期的三个元素—铝、磷、硫原子簇的正负离子的飞行时间质谱。通过对这些质谱的分析研究,列出了在各质谱中出现的“奇幻数”,并讨论了它们可能的结构。
Both positive and negative cluster ions with different sizes and compositions can be generated on a self-built appartus by laser ablation of proper samples in a high vacuum. The mass spectra of cluster cations and anions of four neighboring third period elements Al, Si, P and S are reported and analyzed in this paper. The magic numbers in these spectra are discussed and related to their possible configurations or structure models.
