[PDF] Hyperspherical Harmonics and Generalized Sturmians John Avery (auth.)

From the reviews:
“This book should find its place on the shelves of theoretical chemists as a good companion to other well-known books by this author: “Creation and annihilation operators” and “Quantum theory of atoms,molecules and photons”.”
