Abstract

A positron annihilation experiment on V3Si in the (100) direction is presented. The derivative of the momentum distribution exhibits a complex structure which suggests that the Fermi surface contains planar sections. A theoretical computation of the momentum distribution, on the basis of coupled linear chains, in the independent band approximation is also presented. It provides a possible interpretation of most of the structure appearing in the derivative of the measured momentum distribution.
