A generalization of the Roche potential for eccentric binary orbits in the approximation of quasi-static equilibrium is derived. This potential is used to estimate for the 3U 0900-40 system, the critical radius of the optical primary and the ranges of acceptable inclination angles that are implied by the X-ray eclipse duration. The importance of measuring more accurately the orbital elements and the length of the X-ray eclipse are emphasized. (AIP)
