Hello all, i am looking for a relation to express exp(kCos(gamma)) in spherical harmonics. How can I express it?


thanks

Look in any advanced text in math physics, quantum mechanics or E&M, what you are looking for is the expansion of a plane wave in terms of spherical harmonics and Bessel functions.
 
Thanks for your reply Dr. Transport, I want to use spherical harmonic expansions for exponential functions in a transfer matrix.
