Abstract

A theory of the g-factor of conduction electrons is developed which is valid for low symmetry and arbitrary strength of spin-orbit coupling. Application to bismuth shows that m≡ 2/g≃m ₀ for most orientations, where m ₀ is the effective mass entering the cyclotron frequency. Thus g is 260 when H is in the direction of smallest m ₀. Further, the lifting of the spin degeneracy by the magnetic field introduces a factor cos τπm ₀/m ₈ into the rth oscillatory term in the susceptibility. This explains the apparent phase shift of τπ observed in the de Haas-van Alphen oscillations of Bi.
