Lett. 22, 590 (1969) ] in potassium in a magnetic field directed perpendicular to the surface may be due to an effect of zero-curvature points of the Fermi surface on the cyclotron orbit of effective electrons.2 pages, 1 figure; this is the first work elucidating the part of the local anomalies in the Fermi surface curvature in the origin of the cyclotron resonance in metals in a normal magnetic field; it was not yet available electronicallyMaterials Sciencetext
