Abstract

An electronic bandstructure of the incommensurate linear chain compound Hg_3-δAsF₆ has been calculated by considering various commensurate compounds approximating the real compound. From these calculations a Fermi surface has been determined in qualitative and even close quantitative agreement with experiment. The interchain coupling is found to be strong (≅60mRy) but some corners of the Fermi surface are infinitely sharp because of the screw axis symmetry element of the space group with a concommitant vanishing of the structure constant. This work solves a previously posed dilemma.
