Despite the fact that the magnitude of surface slip, which may occur for a liquid flowing past a solid wall, was quantified by different experimental techniques, the microscopic origin of this effect remains unclear. In the present article we present a neutron reflectivity study for a Newtonian liquid, hexadecane, in contact with solid walls at rest and under shear. In this system slip is not explained by a depleted liquid layer.
