Abstract
The Fermi surface of arsenic has been determined by means of a pseudopotential band-structure calculation. Recent experiments on the de Haas-van Alphen effect permit a more accurate determination of the pseudopotential parameters. The surface consists of three electron pieces located at the point $L$ in the Brillouin zone and the holes are distributed in a multiply connected surface around $T$. The hole surface can be thought of as being formed by six pockets joined by thin cylinders. Good agreement with experiment is found throughout.
