Question
A series involving the product of Green’s function and potential can be obtained by iterating this equation for the T-matrix. For 10 points each:
[10h] Name this equation that relates the kets of the scattered wave function and the scattering potential.. This integral equation is a reformulation of the Schrodinger equation in scattering theory.
ANSWER: Lippman-Schwinger equation
[10m] In scattering, this quantity is measured by taking the shortest perpendicular distance from a projectile’s path to the center of the potential field. For a hard sphere, this quantity is R times the cosine of theta over two.
ANSWER: impact parameter [prompt on b]
[10e] Max Born, who pioneered his namesake approximation in scattering theory, also said that the square of the wave function should be equal to this quantity’s density. When normalized, this quantity should be between 0 and 1.
ANSWER: probability [accept probability density]
