Abstract 



Utilizing the earlier work of Holas et al (2003 Phys. Lett. A 310 451) and the more recent contribution of Akbari et al (2009 Phys. Rev. A 80 032509), we construct an integral equation for the relative motion (RM) contribution t(RM)(r) to the correlated kinetic energy density for modelling twoelectron atoms with harmonic confinement but arbitrary interparticle interaction. It is stressed that t(RM) = t(RM)[f (G)], where f (G) is the atomic scattering factor: the Fourier transform of the density rho(r). As a simple illustrative example of this functional relation for the correlated kinetic energy density, the harmonic Moshinsky case is investigated, the scattering factor then having a Gaussian form.
