【Abstract】 In the square chart of nuclides, it shows systematic regularity for nuclei with even coordinate 18-16. There are seven nuclei with S =18, five nuclei for even coordinate S =16 and 14, three nuclei for S =12,10,8, and 6, which display a regularity of 1,2, and 4 groups. The lower limits of this distribution are all with coordinate H =0. The upper nuclei are centred on the coordinate (12,4) corresponding to nucleus 36 S 20 , which connect the nucleus (6,2) and nucleus (18,6).更多还原
