Scientific paper

Calculations of possible gravitational lens effects have been made in the context of the close QSO pair Q 1548+114A and B, separated on the sky by only 4arcsec.8. Together with current observational constraints, they impose an upper limit of 2×1012M_sun; for the mass of the foreground QSO and an upper limit of 0.3 gm cm-2 for the surface density of any associated cluster. Estimates are made for a range of possible conditions of the properties of any secondary image of the background QSO which may eventually be detected.
