The band structure, the l-projected densities of states, and the Fermi
surface of niobium disilicide have been calculated using the linear M
uffin-Tin Orbital (LMTO) method. The angular dependence of the extrema
l Fermi surface cross-section areas, cyclotron masses, and soft x-my e
mission spectra have been calculated. The agreement with the experimen
tal data is rather good.
