We derive a closed formula for the Baker–Campbell–Hausdorff series expansion in the case of complex matrices. For arbitrary matrices A and B, and a matrix Z such that , our result expresses Z as a linear combination of A and B, their commutator ,

Scattered-wave calculations of X-ray absorption near-edge structure are presented for the K-edge of molecular chlorine. The calculations are based on different choices of one-electron potential: using either overlapped-free-atom or self-consistent-fi

A new approach to multicenter spherical harmonic expansions is presented, which is based on Fourier transform and variational methods. The individual radial functions are optimized simultaneously over all sites at each order of spherical harmonics; a

We describe the testing of a non-maffin-tin extension to the scattered-wave method (due to Natoli, Benfatto and Doniach [Phys. Rev. A 34, 4682(1986)]) for the calculation of one-electron energy eigenvalues and photoionization cross sections of molecu

We outline a many-body description of the photoemission and photoabsorption processes that incorporates the multichannel treatment of the atomic dynamical excitations into the framework of multiple-scattering (MS) theory. This generalization is a mos

We describe progress towards the performance of SCF-SW-Xalpha calculations of photo-absorption cross-sections based on the theory of Natoli et al. for non-muffin-tin potentials. A crucial requirement is the accurate modelling of the electron-molecule

A restricted multiple scattering calculation based on the plane wave approximation but retaining Hankel function terms is presented for zinc bound to four imidazole ligands which is an excellent model for many enzyme active sites. The data show that
