The standard field theory formulations show that the interaction involves an

**exponential**term of the form e ' r° where r0 is related with the mass of theexchanged particle. Such a term makes the interaction fall off sharply with

distance, being ...

Writing f(r) for the common term e /r (which gives the distance dependence — the

Writing f(r) for the common term e /r (which gives the distance dependence — the

**exponential**part merely makes the variables oscillate while the falling off is as Mr) we have from equations (27) and (29) of the last chapter and equation (2) ...
