偶Z>62稳定同位素个数的确定

在参量S—H正方形核素图中,介绍了由稳定区边界的系统规律性,确定稳定同位素偶偶核素个数的一种方法。由偶Z64～82上界,坐标差K=-8～12上界与偶Z80～64下界组成的始于坐标(32,32),经坐标(34,32)(34,36)(36,36)(36,44)(38,44)至上界H44,再向下经坐标(38,42)(40,42)(40,40)(42,40)(42,36)(44,36)(44,32)(42,32)(42,24)至坐标(40,24)的稳定区边界折线形成增量△H=2,4,8与△H=2,2,4,4,8的外围折线。Z>62稳定同位素还由偶Z66～82上界与偶Z64～80下界组成一个对称区,区中存在以常量Z66,68,70;H32,34,36;Z76,78,80为特点的三条递交线。从而确定了偶Z>62各元素的偶偶核素共有46种。

To determine the numbers of stable isotopes for even Z>62

In the square chart of nuclides of parameters with S-H, it introduces a method determining numbers of isotopes base on systematic regularities of stable nuclides region. There are upper limits of even Z64~82 and even difference K = - 8 - 12 and lower limits of even Z80 - 64. They formed a fold-line where it begins coordinate (32,32), passes (34,32) (34,36) (36,36)(36,44)(38,44), goestoH44, and passes (38,42)(40, 42)(40,40) (42,40)(42,36)(44,36) (44.32)(42. 32) (42,24) end (40,24). The coordinates increment of the fold-line is △H = 4,8 and △H = 2,2,4,4,8. There is a symmetry region with upper limits of even Z66~82 and lower limits of even Z80-64. There are three progress fold-lines with constants Z66,68,70, and H32,34, 36 and Z76,78,80. Here it is together 46 even-even nuclei for the region of isotopes Z>62.
