A new approach to the theory of non-ionic chemisorption is proposed which takes account of the strong electron-electron correlation effects on the ad-atom. In analogy to the Heitler-London scheme, the non-orthogonality of the ad-atom and solid wave functions Moncler Jackets Uk Outlet leads to an antiferromagnetic exchange interaction J between the ad-atom and the solid which induces a spin density in the latter near the bonding region. Buy Moncler London The strength of the resultant “induced covalent bond” is measured by Jχloc, where χloc is the local spin susceptibility of the free solid surface. Kingman showed that if the vectorXNis distributed according to the Dirichlet law then the vector of descending order statistics converges, under certain conditions, to a nondegenerate limit. This contrasts with the fact that the limit of any fixed component ofXNis zero. Nevertheless,XNdoes have, in some sense, a nondegenerate limit which we identify with a random interval partition. Convergence of this kind does not require rearranging of the components and implies the existence of limit distributions for a class of functionals which are not covered by the Kingman result.
