Hi,

Messiah writes in his Quantum Mechanics book in chapter XVIII, section 14 (pages 786-789):

What does he mean, when he says "an increment of the order of 'a' is necessary to transform the function phi into a function that is orthogonal to it"? Why do we obtain an orthogonal function, when we increase the atomic distance?

Especially, why should d Phi/ dX be roughly equal to the orthogonal function divided by 'a'?--
