This paper is an extension of Paper 1.2 and notes that a sharp resonance can be obtained if several successive pulses are applied even at random times provided the pulses are all coherently driven by the same oscillator. This demonstration has made possible resonance experiments with the atoms spending most of their time in a large storage box and only occasionally and randomly passing into the oscillatory field region. One such experiment is described in Paper 1.12.
