摘要：
Static electric dipole polarizabilities of lithium clusters made of n (n=2-22) atoms have been measured. The experiment consists of deflecting a collimated cluster beam through a static inhomogeneous electric field. The strong decrease per atom from Li to Li-3-Li-4 shows that electronic delocalization is reached for very small sizes. Moreover, directly measured polarizabilities are consistent with photoabsorption data. They thus confirm unambiguously the ''missing'' optical strength in Lithium clusters. [S1050-2947(99)50301-6].
