关于核素图的研究

The research of diagram of nuclides

习惯上,核素图以原子序数Z为纵坐标,中子数N为横坐标绘制而成。本文试图以质子数为纵坐标、以核素的中子比值n/A为横坐标绘制核素图,这样绘制的核素图可以更清晰地反映出有关核结构的特性,诸如质子和中子的成对性、核素的奇偶性以及核壳层结构的表现等。

It is a general practice in drawing diagram of nuclides that the ordinate represents the proton number Z,and the abscissa the neutron number N. Thio paper proposes to make the ordinate represent the proton number Z,and the abscissa the neutron proportion N/A. The diagram of nuclides drawn in this way can more learly reflect the characteristics of nuclear sfructure such as the stabilities of nuclides. the pairing property of proton and neutron,the add-even of nuclide and the structure of nuclear shell.
