The graphite core–valence–valence Auger spectrum
Surface Science, 2002Abstract The graphite core–valence–valence (CVV) Auger spectrum is analysed, within a one-particle approximation, by comparison to the X-ray excited valence band (VB) photoemission spectrum, whose structure is well understood in terms of the graphite density of states (DOS).

The Valence of Samarium in the Mixed-Valence Transition in SmSe
Japanese Journal of Applied Physics, 1993The microscopic nature of the mixed-valence transition is of fundamental interest. We have used L-edge absorption spectroscopy to measure the valence of SmSe versus pressure at 77K and at 300K. With pressure SmSe undergoes a continuous valence transition as the Sm valence fluctuates between 2+ and 3+. We find that the valence varies with pressure as

A Mixed-Valence Tetranuclear Copper Cluster with Localized Valencies
Inorganic Chemistry, 1997A novel tetranuclear, mixed-valence compound, CuI2CuII2(LL)2Cl6 (LL = dinucleating 4-amino-3,5-bis[(N-methylamino)methyl]-1,2,4-triazole), is described. The molecule consists of a rhomboid of four Cu ions, with short Cu(I)−Cu(II) contacts of 3.875(1) and 4.022(1) A and a Cu(II)−Cu(II) distance of 4.048(1) A. An unusual “sandwich” interaction of 3.193(1)

In the context of politics, the term valence refers to bonds between candidates and some desirable qualities in the public’s mind. This chapter provides a review of formal models of spatial political competition when candidates differ in their exogenous ...

Valence bases for valence-only scattering calculations
Journal of Physics B: Atomic, Molecular and Optical Physics, 1990In a first paper, the authors pointed out that valence-only calculations based on the effective potential of Barthelat et al. (1977) yield satisfactory low-energy electron-molecule scattering results at a reduced computational cost. In the present letter, they explain why this potential seemed superior to more recent ones when the calculation was ...

Engagement valence duality and spillover effects in online brand communities
, 2017Purpose Online brand communities (OBCs) are an effective avenue for brands to engage consumers. While engaging with the brand, consumers simultaneously interact with other OBC members; thus engaging with multiple, interrelated engagement objects

Physical Review Letters, 1992
Since the inception of Density Functional Theory (DFT) the remarkable success of the Local Density Approximation (LDA) has been difficult to improve in a systematic way. Originally Hohenberg, Kohn and Sham introduced LDA as the first term in a gradient expansion of the exchange-correlation energy functional[1].
