The short-range born repulsion originates from strong repulsive forces between atoms due to the overlap of electron clouds as the particles approach the point of contact, which can be determined by the expression developed by Ruckenstein and Prieve (1976) for a sphere-plate system (19) V B = A 132 σ c 6 7560 [8 …

In the hydrogen molecule the bonding depends on the zVzterchange of two … WebMar 27, 2001 · Then the interparticle potential curve is everywhere attractive, up to extremely small separations, where strong repulsive forces (Born repulsion) dominate. Thus, the particles are tightly bound in a primary minimum potential well.
The ionic lattice is modeled as an assembly of hard elastic spheres which are compressed together by the mutual attraction of the electrostatic charges on the ions. They achieve the observed equilibrium distance apart due to a balancing short range repulsion. The electrostatic potential energy, Epair, between a pair of ions of equal and opposite charge is: where WebOne can express the coulombic repulsive force between plates as a potential energy of repulsion. There is another important repulsive force causing a strong repulsion at very small separation distances where the atomic electron clouds overlap, called Born repulsion. [Pg.119]
WebMay 30, 2015 · R: the distance between them. The first term is the attraction energy between the two equal but oppositely charged ions N a + and C l −. The second term is the repulsion between the like charges within the shells. When the distance R is very small, this term has large (opposite) effect. WebInitial point charge assumption does not allow for nuclear-nuclear repulsion at close distances. Correct this empirically: add a term that is repulsive at small r but negligible at larger distances. This means either an exponential term or a 1/r n term with large n. Born repulsion: E rep = B/r n. n is known as the Born exponent, B is an ...
