Abstract
The correlation factor in the explicitly correlated wave function for the ground state of the helium atom has been analyzed. The general structure of the correlation factor (including its angular dependency) in the region of small r12 has been obtained. The `extent of non-sphericityʹ of the correlation factor, g(r1,r2,r12), is proportional to the first derivative of logarithm of the `coalescence functionʹ h(r)=g(r,r,0).
