Getting Started with the Popfly Block SDK,when the electron is far away. We illustrate this by analysing two interesting problems: the energy levels of highly excited states called Rydberg states, in alkali atoms, and the scattering of high energy electrons from atoms and molecules. Though these systems are intrinsically complex, there are

The interaction between the two hydrogen atoms leads to the triplet and singlet states of the H. molecule, which degenerate into a single energy level when the internuclear dist

For the triplet state of the H. molecule, the exchange integral becomes the repulsive part of the potential. However, at large inter-atomic separations, there is always an attraction betwe
