This thesis, after a systematic and in-depth analysis of known nuclides, pro-poses a new model of nuclides’ shell structure and offers a table of the shell structures of 935 nuclides. With this theoretic approach, the thesis studies the shell combination with a bias towards the statistical analysis of nuclide structures. This thesis distinguishes between the basic models of nuclides and gives 7criteria for nuclide binding, the maximal nucleonic number of each shell (Δ
), combination of proton and neutron (p/n
) and graphs of the nuclide growth. Based on magnetic moment, it also conducts a quantitative analysis of p/n
on the shell. The nuclide structure has the characteristic of a shell and on every shell the combination of proton and neutron features clear regularity. Among the 106 elements from
Sg the serial number of the most outside shell in structure is 7, and nuclides Ha and Sg are respectively even A and odd A 7 shells. It is not a coincidence but a reflection of the nuclide shell structure. The thesis uses the result of a statistical analysis to confirm the existence of "the magic Number" and reveals the fact that the magic number" is a reflection of p/n on nuclide shell, particularly on the outer shells. The statistical analysis reveals that the nuclide stability and its way of decay are dependent on the nucleonic combination on the most outside shell and the matching between full-filled and semi-full filled p/n, thus unveiling the general law governing the stability and decay of nuclides.

In 1960s R. Hofstadter, et al conducted the experiment on electronic scattering of high energy and discovered that the average radius of charged particles is 0.8 (F) and the rim thickness is t≈0.4 (F).
