Compact expressions for spherically averaged position and momentum densities.

چکیده
Compact expressions for spherically averaged position and momentum density integrals are given in terms of spherical Bessel functions (j(n)) and modified spherical Bessel functions (i(n)), respectively. All integrals required for ab initio calculations involving s, p, d, and f-type Gaussian functions are tabulated, highlighting a neat isomorphism between position and momentum space formulae. Spherically averaged position and momentum densities are calculated for a set of molecules comprising the ten-electron isoelectronic series (Ne-CH(4)) and the eighteen-electron series (Ar-SiH(4), F(2)-C(2)H(6)).

Correlated electron extracule densities in position and momentum spaces
Spherically averaged extracule densities in position, d(R), and momentum, d̄(P), spaces have been calculated for the atoms helium to neon starting from explicitly correlated wave functions. Correlated values for the electron–electron counterbalance density in position, d(0), and in momentum, d̄(0), spaces, and also for the expectation values ^R& and ^P& are reported. A systematic study of the ele...
متن کاملElectron-pair relative-motion densities of atoms in position and momentum spaces
Spherically averaged electron-pair relative-motion ~intracule! densities h(u) in position space and h̄(v) in momentum space represent probability densities of finding interelectronic position and momentum distances, urj2rku and upj2pku, of any pair of electrons j and k to be u and v , respectively. Using the numerical Hartree-Fock method, these electron-pair densities h(u) and h̄(v) are construct...

Modified functions r−αρ(r) and p−β (p) of the spherically averaged electron densities ρ(r) in position space and (p) in momentum space are found to be convex (i.e., the second derivatives are nonnegative everywhere) for all the 103 ground-state atoms from hydrogen (atomic number Z = 1) to lawrencium (Z = 103), if the parameters are chosen to be α 0.6 and β 1.4. The convex property of r−αρ(r) an...

Spherically averaged center-of-mass-motion ~extracule! densities d(R) in position space and d̄(P) in momentum space represent probability densities of finding center-of-mass radii urj1rku/2 and upj1pku/2 of any pair of electrons j and k to be R and P , respectively. Theoretical analysis shows that in the Hartree-Fock approximation, the individual spin-orbital-pair component of the extracule dens...

Two-electron properties in momentum space for the atoms helium to neon have been calculated starting from explicitly correlated wave functions. The different integrals involved in the calculation have been evaluated by using the Monte Carlo algorithm.
