| Abstract: | Accurate X-ray diffraction data are used to obtain the charge distribution in the superconducting alloy V3Si. The main interaction is found to be strong covalent bonding between adjacent vanadium atoms within the infinite chains. Integration of the charge around the Si and V atoms leads to a best estimate of 1.8–2.4 electrons for the charge transfer from the silicon to the vanadium atoms. |
