L19.2 Energy eigenstates: incident and outgoing waves. Scattering amplitude

[@ScHaERX]

Thank you so much for recording those lectures and doing them so well, at this point I can’t count the number of times this helped me fill gaps lectures at my university left.

To think that at MIT he explains the "solution" in a more intuitive way, an my professor just derived everything using Green's functions... Sometimes more difficult is not better

[@varunmenon830]

I personally like the Green's function derivation more. The spherical wave Ansatz falls out of it quite neatly.

reference book?

[@mitocw]

Actually the syllabus lists seven books: ocw.mit.edu/courses/physics/8-06-quantum-physics-iii-spring-2018/syllabus/. Best wishes on your studies!

(Del^2 + k^2 ) exp( i k r ) = 0
is true, isn't it?

[@chaoyinggu747]

it's not true since Laplace operator in spherical coordinates is not partial/partial r

Nope, here laplacian is in spherical coordinates
