Primer informe sobre estudios de la lluvia radioactiva

THE MIGDAL-JENSEN COLLECTIVE MODEL AND THE WILKINSON SHELL MODEL BOTH GIVE REASONABLE AGREEMENT WITH PHOTONUCLEAR EXPERIMENTS CONCERNING THE INTEGRATED CROSS SECTION, THE RESONANCE ENERGY, AND THE WITH OF THE RESONANCE. WE DISCUSS POSSIBLE REASONS FOR THE SIMILARITY BETWEEN THE PREDICTIONS OF THE TWO DIFFERENTS MODELS. EXPERIMENTS ON EMISSION OF FAST NUCLEONS SHOW THAT THE EXCITED STATE REACHED BY ELECTRIC DIPOLE PHOTON ABSORPTION CONTAINS A LARGE AMPLITUDE OF MODEL WAVE FUNCTIONS REPRESENTING SINGLE PARTICLE EXCITATION.
