  The appearance of peaks in various primordial fluctuation Fourier power
spectra is a generic prediction of the inflationary scenario. We investigate
whether future experiments, in particular the satellite experiment PLANCK, will
be able to detect the possible appearance of these peaks in the B-mode
polarization multipole power spectrum. This would yield a conclusive proof of
the presence of a primordial background of gravitational waves.
