double precision function primitive_value_explicit(power_prim,center_prim,alpha,r)
implicit none
BEGIN_DOC
! Returns the value of the j-th primitive of the i-th |AO| at point $\textbf{r}
! **without the coefficient**
! Evaluates at "r" a primitive of type :
! (x - center_prim(1))**power_prim(1) (y - center_prim(2))**power_prim(2) * (z - center_prim(3))**power_prim(3)
!
! exp(-alpha * [(x - center_prim(1))**2 + (y - center_prim(2))**2 + (z - center_prim(3))**2] )
