Abstract
The pulse-detection method for the observation of the transition to the normal state of superconducting superheated granules measures the percentage of the number of superheated granules as a function of their size for a given applied magnetic field. Two different extrapolations provide : 1) the density of nucleation centres of the normal state and 2) the percentage of superheated granules that would be found if they were defect free. The superheated branch of the hysteresis cycle involving only diamagnetic interactions is drawnKeywords
