摘要

最近关于Na和K的小中性和电离团簇的内聚力的结果用一个简单的Hubbard模型解释,导致传递和库仑积分的值约为0.5至1 eV。这些值证明了Hartree Fock处理电子相互作用的方法是正确的,并且与这些聚集体相当致密的结构相一致。最近关于Na和K - sont在简单的de Hubbard模型下解释的结果一致。这是一种传导积分和库仑积分,在0、5和1 eV阶上。这些估值者证明了“利用”哈特里·福克的“相互作用”、“电子”和“短相干”、“结构”、“紧凑”和“致密”等特性是合理的

On the cohesion of small clusters of alkali metals
Recent results on the cohesion of small neutral and ionised clusters of Na and K are interpreted in a simple Hubbard model, leading to values of transfer and Coulomb integrals of about 0.5 to 1 eV. These values justify the use of a Hartree Fock treatment of electron interactions and are coherent with the fairly compact structures of these aggregates Des resultats recents concernant la cohesion de petits amas neutres et ionises de Na et K sont interpretes dans un modele simple de Hubbard. Ils conduisent a des integrales de transfert et de Coulomb de l'ordre de 0,5 a 1 eV. Ces valeurs justifient l'utilisation d'un traitement de Hartree Fock des interactions electroniques et sont coherents avec les structures assez compactes de ces amas
