N2 - Fluid state trajectories resulting from a step input in power to a He II reservoir, near zero net mass flow, during slow quasi-steady heating have been investigated for normal fluid “outflow” via a duct. The latter is a capillary (diameter range 1 to 100 µm) which connects the reservoir to a main bath. The results obtained for small diameters rule out the possibility of superheating of He II beyond the He II-He I equilibrium state boundary (lambda line), in agreement with the Landau theory of higher order phase transitions.
