氘核的波函数和密度分布的解析形式

Deuteron: analytical forms of wave function and density distribution

V. I. Zhaba

摘要:

氘的波函数可以通过径向波函数的数值的各自的表来表示。在计算这类数字数组的文本程序中操作起来相当困难.因此,采用一种较简单的分析形式是有利的。在已有的坐标表象下的氘核波函数解析形式中,需要计算氘核内的密度分布和跃迁密度,并进行比较。在接收到的核子-核子势的氘核波函数的四种解析形式的系数上,计算了Reid 93的密度分布和跃迁密度。为了比较,对莫斯科势也给出了类似的结果.这样的计算有助于评价波函数近似解析形式选择的正确性,也有助于获得有关氘核的电荷形状因子、张量极化和动量分布等特性的信息。

英文摘要:

The deuteron wave function can be presented as the table through the respective massifs of numerically values of radial wave functions. In calculations such arrays of numbers in the texts of programs to operate quite difficult. Therefore a used simpler analytical forms is expedient. In the received analytical forms of deuteron wave function in coordinate representation it is necessary to calculate density distribution in the deuteron and transition density and compare them among themselves. On the received coefficients of the four analytical forms for deuteron wave function for the nucleon-nucleon potential Reid93 are calculated density distribution and transition density. For comparison, similar results are given for Moscow potential. Such calculations help to evaluate the correctness of the choice of the analytical form for approximation of the wave function, and also to obtain information about such characteristics of the deuteron as charge form factor, tensor polarization and momentum distribution.
