What is the Born approximation and how does it relate to quantum scattering?

[Caglar Yildiz]

Hi i am trying to understand Borh's scattering but i need article that will teach me step by step. Do you know any?

Do you mean the Born approximation? That's just the 1st-order scattering amplitude in usual perturbation theory. You find it in any good textbook on quantum theory. For the formalism, I'd recommend Sakurai, Modern Quantum Mechanics, and to understand the physics and the assumptions underlying the definition of the S-matrix, read the corresponding chapter in Mesiah, Quantum Mechanics, which gives a very concise analysis in terms of the wave-packet approach.
