The effective masses and the Dingle factor for all the oscillations in the (1010) and (1120) planes were determined by measuring, in pulsed magnetic fields up to 150 kOe, the dependence of the oscillation amplitudes in the de Haas--van Alphen effect on the temperature and on the magnetic field. An anomalous angular dependence of the Dingle factor was observed for the Dingle factor at the frequency F/sub gamma/3/ and is attributed to magnetic breakdown. The areas and positions in k-space of the extremal magnetic-breakdown orbits, the parameters v/sub parallel/ and v/sub perpendicular/ at the breakdown points, the gap ..delta.. between the first and second Brilluoin zone at the breakdown points are all calculated. The experimental data are used to estimate the gap ..delta... A possible interpretation, based on magnetic breakdown, is offered for the oscillation frequency f/sub chi/.
