We investigate the optimal kinematic conditions for extracting information about the spatial distribution of neutrons in heavy spin-0 nuclei from a hypothetical parity-violating electron scattering (PVES) experiment. We further investigate the extent to which present uncertainties in the shape of the neutron distribution affect the extraction of the rms neutron radius (the first moment of the distribution [iopmath latex="$R_{{\rm n}}$"] Rn [/iopmath] ). We conclude that present theoretical uncertainties in the shape of the neutron distribution will not preclude a PVES measurement of [iopmath latex="$R_{{\rm n}}$"] Rn [/iopmath] at the [iopmath latex="$1%$"] 1% [/iopmath] level in lead. We also calculate the additional constraints provided by measurements at two different values of the momentum transfer. Finally, we examine the connection to atomic parity non-conservation (PNC) observables and find that a single optimally designed PVES experiment could eliminate nuclear structure uncertainties in future precision tests of the standard model at the sub- [iopmath latex="$1%$"] 1% [/iopmath] level.
