V.I. Zhaba. Deuteron: properties and analytical forms of wave function in coordinate space. e-print arXiv:nucl-th/1706.08306

Abstract: 
Static parameters of the deuteron, 
obtained by the wave functions for various potential models, 
have been chronologically systematized. 
The presence or absence of knots near the origin of coordinates 
for the radial wave function of the deuteron have been shown. 
Analytical forms for the deuteron wave function 
in coordinate space have been reviewed. Both analytical forms 
and parameterizations of the deuteron wave function, 
which are necessary for further calculations of the characteristics 
of the processes involving the deuteron, have been provided. 
In addition, the asymptotic behaviors of deuteron wave function near the origin 
of coordinates and for large values of distance have been analyzed in the paper. 
Minimization of the number of numerically calculated coefficients 
for new analytical forms as a product of exponential function r^n by the sum 
of the exponential terms Ai*exp(-ai*r^3) have been done. The optimum is N=7-10.
