The electron impact excitation of the autoionizing states of helium, their subsequent decay into the same He+1s-1 final ionic state, and the interference of these processes have been studied. We concentrated on the exchange interference of the 2s²(¹S) and 2p²(¹D) states in the 60°-120° scattering angular range. Our evaluation method is based on the comparison of spectra measured at around the critical primary energy (93.15 eV) and the synthetized ones. The peak parameters for the synthetized spectra are obtained from measurement done a few eV below or above the critical energy, where the scattered and ejected electron peaks are well separated.
