1.20 Is True Because 1.19 Is True

The fact that F always equals zero carries through to V(x) always equaling zero if you use the delta function.

I now believe that the delta function is unnecessary. In fact I do not see how to made the derivation work using the delta function even allowing for the integration over the xi=xj point.

What should happen is the in the expression


the integration over the domain of psi2 would pick up f but not xn so that V(x) becomes a function of f as you indicate in eq(2.5) I can get this by excluding xn from the integral, but I cannot get it by integrating over F as you claim to have done. When I integrate over F which is always equal to zero, all I ever get is zero.

So I think your resultis correct, but not the way you did it. But then as in the other post, going from the wave equation to the S eq is a fudge.
