A Photoionization TOF Mass Spectrometric Investigation on Neutral Aluminum Clusters

引用

Chinese Journal of lasers 1997年第5期B6卷 397-402页

作者： ZHAI Huajin NI Guoquan ZHOU Rufang WANG Yuzhu (Laboratory for Quantum Optics, Shanghai Institute of Optics and Fine Mechanics,Chinese Academy of Sciences, P. O. Box 800-211, Shanghai 201800, China) Shanghai Inst of Optics and Fine Mechanics Chinese Acad of Sciences Shanghai China

Neutral aluminum clusters Aln (n up to 30) have been generated using laser vaporization and pulsed molecular beam techniques. The neutral clusters are photoionized by a 193 nm excimer laser and detected by a Wiley-McLaren time of flight (TOF) mass spectrometer. 2p, 1g and 3s electronic shell closings are revealed at Al13,Al19 and Al23, respectively. Geometric effects also contribute to stability the intensity discontinuities, at least within the present investigated cluster size range.

Progress in Natural Science:Materials International 1997年第2期 3-11页

作者：张晓光王秀岩楼南泉 China Chinese Academy of Sciences Dalian 116023 Dalian Institute of Chemical Physics State Key Laboratory of Molecular Reaction Dynamics

Clusters are aggregates of atoms and molecules which are held together by all types of binding forces ranging from weak van der Waals and hydrogen bonding to strong ionic, metallic, covalent, and coordinative bonding, bridging the gap between atoms/molecules and condensed states. The formation and propagation of clusters play an important role in the evolution of
