    "abstract": "A complete theoretical model describing artificial disintegration of nuclei\nby bombardment with alpha-particles, developed by Majorana as early as in 1930,\nis discussed in detail alongside the basic experimental evidences that\nmotivated it. By following the quantum dynamics of a state resulting from the\nsuperposition of a discrete state with a continuum one, whose interaction is\ndescribed by a given potential term, Majorana obtained (among the other\npredictions) the explicit expression for the integrated cross section of the\nnuclear process, which is the direct measurable quantity of interest in the\nexperiments. Though this is the first application of the concept of\nquasi-stationary states to a Nuclear Physics problem, it seems also that the\nunpublished Majorana\u0027s work anticipates by several years the related seminal\npaper by Fano on Atomic Physics.",
