    It is found (experimentally, I think) that the potential between atoms or ions has the behavior given by the 1st equation on page 6, where p and q are integer exponents in that expression. That's pretty much it, they are just the exponents that describe the potential. For two neutral, inert gas atoms, p=12 & q=6 describes the potential. For an ion + neutral atom, p and q will be something else. For two oppositely charged ions, we know that q=1 because of the inverse-square-law for charged particles.

    Hope that helps.
