The quantum level spread is treated in terms of the Dingle temperature, T D . The universal nature of the nonthermal spreading of the Landau levels in solids is established and explained. The importance of the low‐angle scattering of current carriers for the quantum oscillation effects is shown. The effect of the random electrostatic potential fluctuations on the magnitude of the quantum level spread is studied in detail. Experimental data are compared with theory for a wide range of compositions, x , and carrier concentrations, N , in Pb 1 − x Sn x Te alloys.
