摘要
在坐标为S=2Z-N和H=N-Z,单位是氘氚结团的核素图中,研究了稳定区核素分布的基本特点.结果表明,稳定核素主要分布在坐标H与3参量坐标S、差K和S+K(=2S-H)上;列上有连续6种以上偶偶核素的,参量S、K和S+K各有12列,且各参量两两对应,组成3个轴对称的7×8核素区;3条轴线在稳定区中部组成一个小三角形,并与稳定区中最大三角形中心区的小三角形联系,形成一个四边形.
Stable nuclei was discussed in the chart of coordinates with S = 2Z-N, H = N-Z. Stable nuclei mainly distribute on lines of coordinate H and three, parameters co- ordinate S, difference K, parameter S+ K. Continuous region of nuclei distribution for a line, has 6 even-even nuclei was analyzed. The symmetric parameters have 12 lines of three regions. They formed three quadrangles with 7 × 8 nuclei two by two. Three symmetric axes are coordinate S32, difterence K, parameter S + K.
