Correlated one-body momentum density for helium to neon atoms
نویسندگان
چکیده
Starting from explicitly correlated wavefunctions, the one-body momentum density, γ ( E p), and the expectation values 〈δ( E p)〉 and 〈pn〉, with n = −2 to +3, have been obtained for the atoms helium to neon. All the calculations have been carried out by using the Monte Carlo algorithm. An analysis of the numerical accuracy of the method has been performed within the Hartree– Fock framework. The effects of the electronic correlations have been systematically studied by comparing the correlated results with the corresponding Hartree–Fock ones.

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...

In classical systems, the atomic momentum distribution (AMD) is always the renowned Maxwell–Boltzmann distribution.1,2 Essentially, the atomic momentum p = k and atomic position r are independent, canonical variables and the momentum distribution n(k) is always a Gaussian independent of the interatomic or any external potential. Neutron scattering measurements3–10 have shown that n(k) for atoms...
