Scientific paper
Recent observations indicate extra power in the primordial perturbation spectrum at large scales. Non-fiat spectra of adiabatic perturbations generated in a realistic double inflationary model are used to calculate the fluctuations of the microwave background radiation at large, intermediate and small angles. At large angles the predicted temperature fluctuations are in accordance with those predicted by a flat perturbation spectrum. Deviations occur at intermediate and at small angles. Normalizing the calculated temperature fluctuations by the observed COBE quadrupole one can deliver predictions for different small angle experiments. Predictions about the place and the height of a step in the perturbation spectrum could be made from two positive experiments on different small or intermediate angular scales
