WebThis paper investigates how to improve mentally retarded students' interaction which is of utmost importance. As a survey study, the research involves the use of computer-assisted … In molecular physics, the Hamaker constant (denoted A; named for H. C. Hamaker) is a physical constant that can be defined for a van der Waals (vdW) body–body interaction: where ρ1, ρ2 are the number densities of the two interacting kinds of particles, and C is the London coefficient in the particle–particle pair interaction. The magnitude of this constant reflects the strength of the vdW-force between two particles, or between a particle and a substrate.

Webthe dipole field, and the interaction between dipole-2 and the dipole field leads to the dipole-dipole interaction. Based on this idea, we obtain an interaction Hamiltonian for the two magnetic dipoles, which is formally exact and nat-urally has a retarded structure.
