Query: An efficient Multiple Scattering method based on partitioning of
  scattering matrix by angular momentum and approximations of matrix elements   We present a numerically efficient and accurate Multiple Scattering
formalism, which is a generalization of the Multiple Scattering method with a
truncated basis set [X. -G. Zhang and W. H. Butler, Phys. Rev. B 46,7433
(1992)]. Compared to the latter method, we keep the phase shifts of high
angular momenta but apply approximations in the elements of the scattering
matrix which is the subtraction of the unit matrix and the product of
transition operator matrix and structure constant matrix. The detailed
behaviour of our formalism for different types of calculations, where not full
information of Green's function is needed, are discussed. We apply our
formalism to study density of states of fcc Cu and silicon and C K-edge X-ray
absorption spectra of graphene, in order to check the efficiency and accuracy
of our formalism. We find that compared to Zhang's method, the accuracy is
greatly improved by our method.
