[...] The study of the X-ray spectra of elements enabled Moseley at about the same time to settle with certainty the magnitude of the charge of the nucleus and also the number of electrons in outside orbits. [...] These preliminary results have great theoreticail significance; Chadwick has been able 11..oin a tentative determintion of the 4hresh-hold value of the frecwency. of the -/-rays necessary to decompose 'deuterons the mass of the neutron as well as the strolgth of the binding of the two binilamental particles.
