核素分布的漂亮三角形

Pretty Triangle Region for Nuclear Distribution

在氘氚结团为坐标的核素图中,边长11核素的核素分布最大三角形的3顶点为361818Ar180,1365838Ce7820,1967838Pt1184,3边为坐标S38,差K18和参量2S-H=36.最大三角形由4个边长10个坐标单位的小三角形组成,还可由3个6×6核素的菱形组成,3个菱形内部的3个4×4核素组合共有36核素1144830Cd6618,1275232Te7220,1305432Xe7622;中心区有2个最小三角形,其3顶点分别为偶偶核素,奇A核素1195031Sn6919,1255231Te7321,1275332I7421.

On nucleus chart of coordinates with clusters of duteron and triton, three is a maximum triangle of length of three sides with eleven nuclei. Three vertexes of the triangle are , , ,and three sides of that are S = 2Z- N = 38, difference K=S-H= 18 and adding S＋K=36. The triangle is made up of four small triangles with every side 10 coordinate units, or made up by three loznges with 6 × 6 nuclei. There have thirty-six nuclei in the rgion with 4 × 4 nuclei of three lozenges. Three are two minima triangles on the centre part of dig triangle. The three vertexes of the two triangles are even-even nuclei： , , ,and odd-A nuclei： , , ,separately.
