• Based on the quantum lattice gas model, the superfluid transition temperature T. iscalculated for 'He atoms in the model substrate of zeolite. When the density in voidcages and that in pores is different, 7'.is strongly reduced compared with the case thatthe density is homogeneous. In particular, if a pore is longer than a certain length, thesuperfluidity completely disappears under any density. This makes a contrast with thecase of the homogeneous density where T. remains finite for each pore length, Wealso give a general discussion on the competition between the superfluid transitionand the solid-liquid (or liquid-gas) transition of bose particles in zeolite.
