We show that a new fundamental period P f of dHvA oscillations, which appears along with other " forbidden " combination frequencies in a multi-band canonical Fermi-liquid, is very robust with respect to a finite smearing of Landau levels and a background of non-quantized states. We analyse the possibility of measuring small Fermi surface pockets with the use of the " forbidden " frequencies.
