9412618布卢姆菲尔德该计划的目标是通过对原子团簇的研究，发展固体中电子有序的原子和分子观点。通过使用束流和光分离技术研究从二百到五百个原子的原子团簇的电子和磁性，可以考察从简单的原子行为到在块状固体中观察到的行为的转变。这个项目通过对原子团簇的研究，寻找固体中电子有序的原子和分子图景。当原子团的大小从2个原子演化到500个原子时，原子团会从分子过渡到小的固体或液体。通过研究小颗粒中磁性和电学性质的发展，这项研究将提高对原子、分子和凝聚态物质之间关系的理解。这些研究将提供对金属和非金属行为以及金属-非金属转变的分子起源的理解。***

9412618 Bloomfield The objective of the program is to develop an atomic and molecular viewpoint for electronic ordering in solids through the study of atomic clusters. By examining the electronic and magnetic properties of clusters of atoms from two to five hundred atoms using beam and photodetachment techniques, it is possible to examine the transition from simple atomic behavior to that observed in bulk solids. % % % This project seeks an atomic and molecular picture for electronic ordering in solids through the study of atomic clusters. As they evolve in size from 2 to 500 atoms, clusters of atoms make a transition from molecules to small solids or liquids. By studying the development of magnetic and electronic properties in small particles, the research will improve the understanding of the relationship between atoms, molecules, and condensed matter. Such studies will provide understanding of the molecular origins of metallic and nonmetallic behaviors as well as metal-nonmetal transitions. ***
