The book "Radial Basis Function Methods For Large-Scale Wave Propagation", details the development of techniques and ideas from the radial basis function. It begins with a mathematical description of ...

If P(nl; r) is the (nl) radial wave function in an atom of atomic number N, and PH(nl; r) is the corresponding wave function of hydrogen, then, for a given configuration and for large N N-1/2P(nl; r) ...
