Uranyl Ion Complexation by Aliphatic Dicarboxylic Acids in the Presence of Cucurbiturils as Additional Ligands or Structure-Directing Agents
TL;DR: A series of nine complexes has been obtained from the hydrothermal reaction of uranyl nitrate with long-chain alkyldicarboxylic acids (HOOC-(CH2)n-2-COOH, denoted H2Cn) in the presence of cucurbit[6]uril (CB6), dimethylformamide (DMF), and additional alkaline-earth metal ions in some cases as discussed by the authors.

A semi-empirical method of absorption correction
TL;DR: An extension of Furnas's method is described in this paper, where the variation of intensity of an axial reflection as the crystal is rotated about the goniometer axis is used to give a curve of relative transmission T against azimuthal angle ϕ for the corresponding reciprocal lattice level.

X-ray scattering factors computed from numerical Hartree–Fock wave functions
D. T. Cromer,J. B. Mann +1 more
TL;DR: In this paper, the Hartree-Fock wave function was used to compute X-ray scattering factors for neutral atoms from He to Lw and for most of the chemically significant ions through Lu3+ through Lu 3+.

Relativistic Calculation of Anomalous Scattering Factors for X Rays
Don T. Cromer,David A. Liberman +1 more
TL;DR: In this paper, relativistic calculations of the photoelectric cross section have been made and the integral for the principal contribution to Δf′ has been evaluated numerically without approximation to the form of the cross section-vs-energy curve, as has been done in previous calculations.
